Résumé :
The importance of natural resources in sustaining productivity and environmental protection is now relatively more realized than the past. Over the past few decades or so, more and more attention is being paid all over the world to conserve the Natural Resources. Natural resources are important material basis for a stable economy and social development too With Industrialization and Urbanization, mankind’s great demand for natural resources and their large scale exploitation and consumption has resulted in the weakening, deterioration and exhaustion of these resources. Human existence depends on the natural resources and the environment and the maintenance of which is now increasingly being considered as essential for mankind. As human populations increase and natural resources become more limited, there is a critical need for trained conservation professionals in natural resources conservation. Natural Resources are those environmental gifts which satisfy the human wants. They are the means of attaining social objectives. Conservation of natural resources is the wise use of the earth's resources by humanity to achieve its benefits for the longest possible period of time and ensure availability of these resources for the further generation. One difficult task faced by all countries is to guarantee the lasting utilization of natural resources at the lowest possible environmental cost while still assuring economical and social development.

Résumé :
The survival and progress of human life depends on developmental resources. Since ancient times human beings get various types of things from nature and fulfill their needs. In fact, resources are those which are useful to human beings, human beings are a part of the environment just like other organisms but a variation which is easily reflected. That is, human beings have sufficient ability to affect the environment around them and control them in some sense as compared to other organisms. That is why human relations with environment are given so much importance.In modern life, there is nothing more curious than the problem of human and environmental relations. The pace of this awareness has been slow in the developing countries and its solution has just started to be fully realized.The global dimension of environmental awareness is beginning to appear in some decades. It has been felt that the unpredictable loss of land, air, water etc. is being done by the nature system of the earth, the future survival of the organisms on earth is starting to be threatened, now there is a need to think holistically. It is known that the object of the world is in our hands.Man has also had to bear the consequences of contempt for nature. Due to all this, a strong need is being felt today that how the above balance of nature can be regained, now we have to use our technical skills in ways to reclaim our lost environment. मानव जीवन का अस्तित्व, प्रगति विकास संसाधनों पर निभ्रर करता है । आदिकाल से मनुष्य प्रकृति से विभिन्न प्रकार की वस्तुएँ प्राप्त कर अपनी आवष्यकताओं को पूरा करता है वास्तव में संसाधन वे है जिनकी उपयोगिता मानव के लिए हो, अन्य जीवों के समान ही मानव भी पर्यावरण का ही एक अंग है परन्तु एक विभिन्नता जो सहज ही परिलक्षित होती है वह यह है कि अन्य जीवों की तुलना में मानव अपने चारों ओर के पर्यावरण को प्रभावित तथा कुछ अर्थो में उसे नियंत्रित कर पाने की पर्याप्त क्षमता है यही कारण है कि मानव का पर्यावरण के साथ संबंधों को इतना महत्व दिया जाता है ।आधुनिक जीवन में मानव तथा पर्यावरण के संबंधों की समस्या से अधिक उत्सुकता का अन्य कोई विषय नहीं है । इस जागरूकता की गति विकासषील देषों में मंद रही है तथा इसका समाधान संपूर्णता से अभी-अभी ही अनुभव किया जाने लगा है । विगत् कुछ दषकों में पर्यावरणीय सजगता का वैष्विक आयाम प्रकट होने लगा है । यह महसूस किया गया है कि पृथ्वी की प्रकृति व्यवस्था से भूमि, वायु, जल आदि का अप्रत्याषित नुकसान किया जा रहा है पृथ्वी पर जीवों की भावी उत्तरजीविता को खतरा उत्पन्न होने लगा है अब समग्र रूप से सोचने की आवष्यकता पड़ रही है अब यह महसूस किया जाने लगा है कि विष्व का शग्य हमारे हाथो में है ।मनुष्य को प्रकृति के प्रति तिरस्कार का परिणाम भी सहना पड़ा है । इस सबके कारण ही आज इस बात की प्रबल आवष्यकता अनुभव की जाने लगी है कि किस प्रकार प्रकृति का उपर्युक्त संतुलन पुनः प्राप्त किया जा सकता है अब हमें अपने तकनीकी कौषल का उपयोग अपने खोये हुए पर्यावरण को पुनः प्राप्त करने के तरीकों में करना होगा ।

Résumé :
Nature has provided all the useful resources to man with free hand. Adivana relied entirely on nature to fulfill all its needs, but in the development of Adivasi from human to modern man, man exploited the natural resources in full and consequently the abundant wealth of nature gradually started to end. In this sequence, various species have reached the category of extinct species, conservation of natural resources has become imperative to preserve the remaining species and the human species itself. Along with taking various protective measures for this, the need is for the youth who are sensitive to nature and able to bear the responsibility of conservation of natural resources by staying in the nature of nature even in odd circumstances. प्रकृति ने मनुष्य को सभी जीवनोपयोगी संसाधन मुक्त हस्त से प्रदान किये हैं। आदिमानव अपनी समस्त आवष्यकताओं की पूर्ति के लिये पूरी तरह प्रकृति पर निर्भर करता था, किंतु आदि मानव से आधुनिक मनुष्य बनने की विकासयात्रा में मनुष्य ने प्राकृतिक संसाधनों का भरपूर दोहन किया फलस्वरूप प्रकृति की अकूत संपदा धीरे-धीरे समाप्त होने लगी। इस क्रम में विभिन्न प्रजातियाँ विलुप्त प्रजातियों की श्रेणी में पहुँच गयीं, शेष बची हुई प्रजातियों और स्वयं मनुष्य प्रजाति को बचाये रखने के लिये भी प्राकृतिक संसाधनों का संरक्षण अत्यावष्यक हो गया है। इस हेतु विभिन्न सुरक्षात्मक कदम उठाने के साथ-साथ आवष्यकता ऐसे युवाओं की है जो प्रकृति के प्रति संवेदनषील हों तथा विषम परिस्थितियों में भी प्रकृति के सानिध्य में रहकर प्राकृतिक संसाधनों के संरक्षण का उत्तरदायित्व निभाने में सक्षम हों।

Résumé :
Integrating cultural and natural resources for large landscape conservation remains an applied challenge for landscape planners and resource managers across North America. When resources are considered at a regional scale, developing shared priorities, definitions, and metrics is an essential but complex process for successful conservation partnerships. Strategies exist for designing regional conservation models for natural resources, but methods for cultural resource conservation planning often remain focused on individual sites and buildings. Here, we build on our previous work with the Landscape Conservation Cooperatives to advance frameworks and spatial models for regionally integrated natural and cultural resource conservation design and planning. Specifically, we present the results of our survey of cultural resource specialists in the Mid-Atlantic region of the United States to better understand how cultural resources are defined, classified, and valued by this group. Methods from applied cognitive anthropology are useful for uncovering cultural consensus and more marginalized perspectives around resource management priorities, offering a clear pathway for integrating cultural and natural resource conservation. We conclude by restating a call for a National GAP-like research program for cultural resources that integrates diverse cultural practices, perspectives, histories, and values of communities for designing future conservation priorities.

Résumé :
Conservation of natural resources is a natural resource management whose utilization is done wisely to ensure the continuity of its availability by maintaining and improving the quality of diversity and value. Conservation of natural resources and ecosystems aims to achieve the realization of the sustainability of natural resources and the equilibrium of the ecosystem so that it can better support the efforts to improve the community welfare and the quality of human life. The problem are the implementation of conservation of natural resources and its ecosystem in the region based on Act No. 5 of 1990 and law enforcement against perpetrators of the conservation of natural resources and ecosystems. The research method used is legal research using a statutory and conceptual approach. The conservation of natural resources and ecosystems is based on preserving the ability and utilization of natural resources and their ecosystem in a harmonious and balanced environment. The conservation of natural resources and ecosystems is conducted through the protection of life-supporting systems, preserving the diversity of plant and animal species along with its ecosystem and the sustainable utilization of natural resources and ecosystem.

Résumé :
Managing for the long-term survival of a species requires an understanding of its population genetics. The desert tortoise, Gopherus agassizii, inhabits the Mojave and Sonoran deserts of North America. Desert tortoises face many threats to their continued survival, including habitat loss and fragmentation. I used mitochondrial and microsatellite DNA markers to examine genetic structure within and among populations of desert tortoises. I found that both the Mojave and Sonoran populations of desert tortoise exhibit similar patterns of population genetic structure. Gene flow among localities within each region is part of the evolutionary history of the desert tortoise and dispersal events probably play an important role in the long-term maintenance of populations. Movement barriers caused by anthropogenic landscape changes have the potential to effect desert tortoise population viability. Understanding the historical connectivity between and within the Mojave and Sonoran populations of desert tortoises will help facilitate the conservation of this species.

Résumé :
Sustainability of natural resources is currently a concern worldwide. The ecological and economic aspects of sustainability have received substantial research attention, but the social aspects of sustainability are less well understood. Participation by affected communities in natural resource management decisions is pivotal to social sustainability. As such, this study examined ten case studies of participation and decision-making by natural resource management groups involved in agriculture in the south-west of Australia. Groups at four spatial scales were studied, including the State, regional, land conservation district (Shire) and subcatchment. Drawing on these ten case studies, this study analysed participation in these groups from the perspectives of representation, leadership and partnership. Crucial elements of this analysis included identifying the desirable attributes of participation in terms of achieving social sustainability, and then comparing current practice against these ideals. The study concludes with comments about the efficacy at each spatial scale of current approaches to participation in terms of social sustainability. Central conclusions from this study follow. Some scales are performing better than others in terms of meeting the expectations expressed through the desirable criteria. The State scale is performing well, in terms of its mandate, with its lower expectations than those ascribed to regional and subcatchment scales clearly being met. On the other hand, the expectations associated with the community- and government-led regional groups and subcatchment groups are enormous. The only place where there was any major difference between the three was in representation: it was barely considered by respondents from the subcatchment groups, while for the regional groups less of the expectations were met by the community-led than government-led groups. Otherwise they were very similar. The land conservation districts, caught between the regions and subcatchments, seem to be faring the poorest.

Résumé :
The protection of natural resources during an ongoing climate crisis can be viewed not only as a precondition for natural ecosystems but for social and economic ecosystems as well. At the same time, localization of natural resource protection within rural development issues includes the involvement of local inhabitants both in terms of attitude and practical involvement as an important precondition for sustainable regional development. Based on quantitative data gathered from the project "Ready for change? “Sustainable management of common natural resources” this article aims to reveal attitudes towards protection and readiness to involve in the protection of natural resources of Gauja National Park inhabitants. Data from a representative quantitative survey reveal that local inhabitants of Gauja National Park have high expected responsibility from various actors for the preservation and protection of natural resources. Expected responsibility can also be well explained by the concept of shared responsibility. It can also be concluded that there is broad agreement on the representation of interests of local inhabitants in the Nature conservation plan regardless of civic engagement or involvement in the protection of natural resources – either operationalized as involvement intensity in various dimensions of nature protection or in embedded readiness to involve or involvement in nature protection.

Résumé :
Water is a “renewable, vulnerable and limited natural resource, an indispensable element for life and society, raw material for productive activities, energy source and transport, decisive in maintaining the ecologi­cal balance.” But is water, really, an inexhaustible and permanently renew­able element? This is the question that can only be answered by implement­ing all methods, levers, domestic and international efforts aimed at protect­ing water and maintaining its natural and permanent circuit in nature. As water is a natural resource with great economic value in all its forms of use, conservation, reuse and saving of water are imperative objectives, which are to be achieved through the development of environmental awareness, the application of economic stimulus and the application of sanctions to those which violate legal rules on water protection. The protection of water quality at the national and international level involves a vast and complex activity of cooperation and collaboration based on domestic legislation and international treaties and conventions to which Romania is a party. The planet’s waters are a unitary whole, but their legal protection regimes vary depending on the category of waters that are protected. As a result of the diversity of legal regimes for water protection, the need for international cooperation has been imposed in order to prevent and combat water pol­lution, its judicious administration and management. The main normative acts include objectives and rules such as conservation, development and protection of water resources, protection against any forms of pollution and modification of water characteristics, complex use of water as an economic resource, their rational and balanced distribution, conservation and protec­tion of aquatic ecosystems, protection against floods and other dangerous hydrometeorological phenomena, meeting the water requirements of in­dustry, agriculture, tourism, transport and any human activities.

Texte intégral
Résumé :
The wetlands of the lower Songkhram River basin are protected as a Ramsar site and a regional environmental asset, but they are under threat from numerous factors related to developmental activities. The lower Songkhram River is the last free-flowing tributary of the Mekong River and is a lifeline for over 14 000 households and a haven to many endemic biodiversity species. Local communities in the region have unique associations with the natural resources in the river basin, including the wetlands, and they perceive immense value in conserving these ecosystems. Natural resource policies lack specific guidelines and collaborative approaches for the protection, conservation and management of the wetland resources of the lower Songkhram River. The way forward should be led by a synchronized planning process, collaborative governance of the wetland resources, and empowerment of already existing local community groups.

Résumé :
Tetepare, an island in the Western Province of the Solomon Islands, is the largest uninhabited tropical island in the Southern Hemisphere. Tetepare has a largely intact wilderness, with remarkable biodiversity of globally significant conservation importance. This case study explores the biodiversity of Tetepare and efforts to maintain Tetepare as “the last wild island.” In response to threats by the extractive logging industry, the landowners of the island – Solomon Islanders descended from Tetepare’s original inhabitants - formed what is today known as the Tetepare Descendants’ Association (TDA), an organization that manages and conserves the island and its resources. TDA members receive benefits through a community conservation agreement (CCA): in return for conserving the land and rejecting all commercial exploitative industries, members receive benefits including scholarships, sustainable livelihood development, and employment opportunities. Tetepare’s conservation serves as an example of landowners successfully leveraging their natural inheritance to sustainably meet the economic needs of their communities without sacrificing the natural heritage of future generations.

Résumé :
In a collaborative effort to advance climate adaptation resources available to wetland practitioners, the Wisconsin Initiative on Climate Change Impacts (WICCI) and the Northern Institute of Applied Climate Science (NIACS) have partnered to create adaptation resources for non-forested wetland management. This effort is also supported by the USDA Northern Forests Climate Hub. This publication provides perspectives, information, resources, and tools to wetland managers and natural resource professionals in the Midwest and Northeast regions of the United States as they endeavor to adapt natural communities and ecosystems to the anticipated effects of climate change. In this publication, we identify potential strategies and approaches that facilitate climate adaptation while meeting wetland conservation or restoration management goals and objectives. Adaptation strategies and approaches are intended to build upon current management actions that work to sustain ecosystems over the long term and support site goals while also adjusting systems to changing conditions. While it is beyond the scope of this publication to comprehensively address all potential adaptation tactics applicable to the conservation of wetlands, we provide examples to guide thinking, recognizing that individual wetland management projects have unique goals. Wetland professionals, reliant on their expertise and judgement, can use the adaptation strategies and approaches presented in this document to develop custom adaptation tactics based on the local conditions

Texte intégral
Résumé :
The National Park Service (NPS) Natural Resource Condition Assessment (NRCA) Program administered by the NPS Water Resources Division evaluates current conditions for important natural resources and resource indicators using primarily existing information and data. NRCAs also report on trends in resource condition, when possible, identify critical data gaps, and characterize a general level of confidence for study findings. This NRCA complements previous scientific endeavors, is multi-disciplinary in scope, employs a hierarchical indicator framework, identifies and develops reference conditions/values for comparison against current conditions, and emphasizes spatial evaluation of conditions where possible. Lincoln Boyhood National Memorial (LIBO) was authorized by an act of Congress on February 19, 1962, (Public Law 87-407) to preserve the site associated with the boyhood and family of President Abraham Lincoln, including a portion of the original Tom Lincoln farm and the nearby gravesite of Nancy Hanks Lincoln. The 200-acre memorial commemorates the pioneer farm where Abraham Lincoln lived from the age of 7 to 21. The NRCA for LIBO employed a scoping process involving Colorado State University, LIBO and other NPS staffs to establish the NRCA framework, identify important park resources, and gather existing information and data. Indicators and measures for each resource were then identified and evaluated. Data and information were analyzed and synthesized to provide summaries and address condition, trend and confidence using a standardized but flexible framework. A total of nine focal resources were examined: four addressing system and human dimensions, one addressing chemical and physical attributes, and four addressing biological attributes. The quality and currentness of data used for the evaluation varied by resource. Landscape context ? system and human dimensions included land cover and land use, natural night skies, soundscape, and climate change. Climate change and land cover/land use were not assigned a condition or trend?they provide important context to the memorial and many natural resources and can be stressors. Some of the land cover and land use-related stressors at LIBO and in the larger region are related to the development of rural land and increases in population/housing over time. The trend in land development, coupled with the lack of significantly sized and linked protected areas, presents significant challenges to the conservation of natural resources of LIBO to also include natural night skies, natural sounds and scenery. Climate change is happening and is affecting resources, but is not considered good or bad per se. The information synthesized in that section is useful in examining potential trends in the vulnerability of sensitive resources and broad habitat types such as forests. Night skies and soundscapes, significantly altered by disturbance due to traffic, development and urbanization, warrant significant and moderate concern, respectively, and appear to be in decline. Air quality was the sole resource supporting chemical and physical environment at the memorial. The condition of air quality can affect human dimensions of the park such as visibility and scenery as well as biological components such as the effect of ozone levels on vegetation health. Air quality warrants significant concern and is largely impacted by historical and current land uses outside the memorial boundary. The floral biological component was examined by assessing native species composition, Mean Coefficient of Conservation, Floristic Quality Assessment Index, invasive exotic plants, forest pests and disease, and forest vulnerability to climate change. Vegetation resources at LIBO have been influenced by historical land uses that have changed the species composition and age structure of these communities. Although large tracts of forests can be found surrounding the park, the majority of forested areas are fragmented, and few areas within and around LIBO exhibit late-successional or old-growth characteristics. Vegetation communities at LIBO have a long history of being impacted by a variety of stressors and threats including noxious and invasive weeds, diseases and insect pests; compounding effects of climate change, air pollution, acid rain/atmospheric chemistry, and past land uses; and impacts associated with overabundant white-tail deer populations. These stressors and threats have collectively shaped and continue to impact plant community condition and ecological succession. The sole metric in good condition was native species composition, while all other indicators and metrics warranted either moderate or significant concern. The faunal biological components examined included birds, herptiles, and mammals. Birds (unchanging trend) and herptiles (no trend determined) warrant moderate concern, while mammal populations warrant significant concern (no trend determined). The confidence of both herptiles and mammals was low due to length of time since data were last collected. Current forest structure within and surrounding LIBO generally reflects the historical overstory composition but changes in the hardwood forest at LIBO and the surrounding area have resulted in declines in the avian fauna of the region since the 1970s. The decline in woodland bird populations has been caused by multiple factors including the conversion of hardwood forest to other land cover types, habitat fragmentation, and increasing human population growth. The identification of data gaps during the course of the assessment is an important NRCA outcome. Resource-specific details are presented in each resource section. In some cases, significant data gaps contributed to the resource not being evaluated or low confidence in the condition or trend being assigned to a resource. Primary data gaps and uncertainties encountered were lack of recent survey data, uncertainties regarding reference conditions, availability of consistent long-term data, and the need for more robust or sensitive sampling designs. Impacts associated with development outside the park will continue to stress some resources. Regionally, the direct and indirect effects of climate change are likely but specific outcomes are uncertain. Nonetheless, within the past several decades, some progress has been made toward restoring the quality of natural resources within the park, most notably the forested environments. Regional and park-specific mitigation and adaptation strategies are needed to maintain or improve the condition of some resources over time. Success will require acknowledging a ?dynamic change context? that manages widespread and volatile problems while confronting uncertainties, managing natural and cultural resources simultaneously and interdependently, developing disciplinary and interdisciplinary knowledge, and establishing connectivity across broad landscapes beyond park borders.

Conservation of freshwater biodiversity has been seriously neglected throughout the world, and entire ecosystems are threatened with extinction. Unfortunately, freshwater sustainability issues do not appear to be a primary consideration in the planning and implementation of water use projects, nor in the allocation of use permits. This paper discusses the value and function of Latin American freshwater ecosystems and gives a comprehensive approach to developing a sustainable water resources management policy.

Résumé :
Climate changes are affecting virtually all National Park Service units and resources, and an assessment of climate vulnerabilities is important for developing proactive management plans to respond appropriately to these changes and threats. Vulnerability assessments typically evaluate exposure and sensitivity of the assessment targets and evaluate adaptive capacity for living resources. Chapters in this report review and evaluate climate vulnerability assessments of National Park Service units and resources including infrastructure, natural resources, and cultural resources. Striking results were the diversity of approaches to conducting vulnerability assessments, the small number of vulnerability assessments for National Park Service cultural resources, and the large differences in the “state of the science” of conducting assessments among the three resource groups. Vulnerability assessment methodologies are well established for evaluating infrastructure and natural resources, albeit with very different techniques, but far less is known or available for designing and/or conducting cultural resources assessments. Challenges consistently identified in the vulnerability assessments, or the chapters were: Limited capacity of park staff to fully engage in the design and/or execution of the vulnerability assessments. Most park staff are fully engaged in on-going duties. Inconsistent use of terms, definitions, and protocols, sometimes resulting in confusion or inefficiencies. Discovering and acquiring National Park Service vulnerability assessments because results were inconsistently archived. Aligning results with park needs due to differences in level of detail, scope, and/or resolution, or format(s) for reporting results. Best practices and recommendations identified in multiple chapters were: Ensure that vulnerability assessments are designed to match parks’ needs, and that results are reported in ways that inform identified management decisions. Prioritize resources to be thoroughly assessed so effort is directed to the most important threats and resources. Evaluate all components of vulnerability (not just exposure). Explicitly and systematically address uncertainty, recognizing the range of climate projections and our understanding of potential responses. Identify and, where possible, focus on key vulnerabilities that most threaten conservation or management goals. Embrace partnerships and engage others with necessary expertise. Good vulnerability assessments usually require expertise in a broad range of subject areas.

Résumé :
Natural Resource Condition Assessments (NRCAs) evaluate current conditions of natural resources and resource indicators in national park units (parks). NRCAs are meant to complement—not replace—traditional issue- and threat-based resource assessments. NRCAs employ a multi-disciplinary, hierarchical framework within which reference conditions for natural resource indicators are developed for comparison against current conditions. NRCAs do not set management targets for study indicators, and reference conditions are not necessarily ideal or target conditions. The goal of a NRCA is to deliver science-based information that will assist park managers in their efforts to describe and quantify a park’s desired resource conditions and management targets, and inform management practices related to natural resource stewardship. The resources and indicators emphasized in a given NRCA depend on the park’s resource setting, status of resource stewardship planning and science in identifying high-priority indicators, and availability of data and expertise to assess current conditions for a variety of potential study resources and indicators. Puʻuhonua o Hōnaunau National Historical Park (hereafter Puʻuhonua o Hōnaunau NHP) encompasses 1.7 km2 (0.7 mi2) at the base of the Mauna Loa Volcano on the Kona coast of the island of Hawaiʻi. The Kona coast of Hawaiʻi Island is characterized by calm winds that increase in the late morning to evening hours, especially in the summer when there is also a high frequency of late afternoon or early evening showers. The climate is mild, with mean high temperature of 26.2° C (79.2° F) and a mean low temperature of 16.6° C (61.9° F) and receiving on average 66 cm (26 in) of rainfall per year. The Kona coast is the only region in Hawaiʻi where more precipitation falls in the summer than in the winter. There is limited surface water runoff or stream development at Puʻuhonua o Hōnaunau NHP due to the relatively recent lava flows (less than 1,500 years old) overlaying much of the park. Kiʻilae Stream is the only watercourse within the park. Kiʻilae Stream is ephemeral, with occasional flows and a poorly characterized channel within the park. A stream gauge was located uphill from the park, but no measurements have been taken since 1982. Floods in Kiʻilae Stream do occur, resulting in transport of fluvial sediment to the ocean, but there are no data documenting this phenomenon. There are a small number of naturally occurring anchialine pools occupying cracks and small depressions in the lava flows, including the Royal Fishponds; an anchialine pool modified for the purpose of holding fish. Although the park’s legal boundaries end at the high tide mark, the sense of place, story, and visitor experience would be completely different without the marine waters adjacent to the park. Six resource elements were chosen for evaluation: air and night sky, water-related processes, terrestrial vegetation, vertebrates, anchialine pools, and marine resources. Resource conditions were determined through reviewing existing literature, meta-analysis, and where appropriate, analysis of unpublished short- and long-term datasets. However, in a number of cases, data were unavailable or insufficient to either establish a quantitative reference condition or conduct a formal statistical comparison of the status of a resource within the park to a quantitative reference condition. In those cases, data gaps are noted, and comparisons were made based on qualitative descriptions. Overall, the condition of natural resources within Puʻuhonua o Hōnaunau NHP reflects the surrounding landscape. The coastal lands immediately surrounding Puʻuhonua o Hōnaunau NHP are zoned for conservation, while adjacent lands away from the coast are agricultural. The condition of most natural resources at Puʻuhonua o Hōnaunau NHP reflect the overall condition of ecological communities on the west Hawai‘i coast. Although little of the park’s vegetation...
