Annotation:

The Himalayan Red Panda Ailurus fulgens (Cuvier, 1825) is a globally Endangered species whose population is reported to be declining in the wild. It is a priority species for the Neora Valley National Park (NVNP) since it is the flagship species of this ecosystem. Moreover, this landscape functions as an important connecting link of the Himalayan Red Panda habitat between the state of West Bengal and Sikkim. The spatial habitat of the Himalayan Red Panda in this National Park is little known. Our study attempts to identify the spatial distribution of potential habitats for the Himalayan Red Panda using the maximum entropy algorithm (MaxEnt 3.4.1). The model predicted a 55 km2 of potential habitat with the current climate scenario. With climate change, predicted potential habitats are likely to experience significant loss and upward shift to a relatively higher elevation. Hence, the management of the NVNP should identify the potential habitats and accomplish realistic goals to help conserve the Red Pandas.

Annotation:

The purpose of this study was to determine attitudes of Verde Valley residents toward the presence of National Park Service (NPS) units in the area. The study area is largely undeveloped rural land which includes a perennial riparian expanse along the Verde River in central Arizona. Three National Park Service units protect significant local archaeological relics. The general public and local land use decision makers were polled, using random mail surveys and telephone interviews, to determine local values toward economic, visual, cultural, historic and natural resource issues. Responses from each group were compiled and compared for similarities and significant divergence. Results indicate this is a fairly satisfied community which highly values local natural and scenic resources but values the cultural/historic resources to a lesser degree. Results also indicate a lack of association between the relationship of the Verde River and other natural resources with the presence of NPS units.

Annotation:

Parks Canada uses park management planning to put into practice the dual mandate of protecting environmentally significant areas and providing for recreational activities within those areas. A park management plan lays out the objectives and strategies to indicate how each national park will protect and represent its natural and cultural heritages. A geographic information system (GIS) can support park management planning by providing the concepts of a data base management system and the capabilities of transforming spatial data into information through data integration, analysis-synthesis, and communication. Park management planning of a section of the Alsek River valley of Kluane National Park Reserve in the Yukon Territory requires the use of specific GIS concepts and capabilities. A three-phase GIS framework focusing on the pre-conditions to GIS application, the GIS application, and the GIS application evaluation is used to define the necessary concepts. The capabilities include acting as an inventory, analysis-synthesis or management tool to contribute to mapping, monitoring, and modelling the valley's resources and visitor activities.

Annotation:

In recent years, mapping software utilizing scanned?or ?softcopy??aerial photographs has become widely available. Using scanned photos of Valley Forge (PA) National Historical Park, I explored some of the latest tools for image processing and computer-based vegetation mapping. My primary objective was to compare different approaches for their efficiency and accuracy. In keeping with the USGS-NPS Vegetation Mapping Program protocol, I classified the park?s vegetation according to The Nature Conservancy?s National Vegetation Classification System (NVCS).

Initially, I scanned forty-nine 1:6000 color-infrared air photos of the area at 600 dpi using an Epson desktop scanner. I orthorectified the images by two different methods. First, I did so on a single-image basis using ERDAS Imagine. In this approach, United States Geological Survey (USGS) Digital Ortho Quarter Quadrangles (DOQQ) and a 10-meter Digital Elevation Model (DEM) served as references for between seven and twelve ground control points per photo. After achieving a root mean square error (RMSE) of less than 1 meter for an image, I resampled it into an orthophoto. I then repeated the process using Imagine Orthobase. Via aerial triangulation, Orthobase generated an RMSE solution for the entire block of images, which I resampled into orthophotos using a batch process.

Positional accuracies were remarkably similar for image mosaics I created from the single-image as well as the Orthobase orthophotos. For both mosaics, planimetric x-coordinate accuracy met the U.S. National Map Accuracy Standard for Class 1 maps, while planimetric y-coordinate accuracy met the Class 2 standard. However, the Orthobase method is faster?reducing process time by 50%?and requires 20% (or less) of the ground control points necessary for the single-image method.

I delineated the park?s vegetation to the formation level of the NVCS. Using ESRI ArcMap, I digitized polygons of homogeneous areas observed from the orthophotos. This on-screen mapping approach was largely monoscopic, though I verified some areas using a scanning stereoscope and the original hard-copy photos. The minimum mapping unit (MMU) was 0.5 acres (ac), smaller than that recommended by the USGS-NPS protocol. Based on field data, thematic accuracy for this map met the National Map Accuracy Standard of 80%. Misestimation of the hydrologic period of certain polygons resulted in some classification errors, as did confusion between evergreen and deciduous vegetation.

In addition to orthophotos, Orthobase creates a stereo block viewable in ERDAS Stereo Analyst, a digital stereoscopic software package. Using Crystal Eyes? eyewear and a high-refresh-rate monitor, a user can observe imagery full screen, three-dimensionally. Features delineated on the images are stored in ESRI shapefile format. I created a preliminary vegetation map at the alliance level of the NVCS with this software. Thematic accuracy of this map will be known when assessment is completed this summer. Notably, the classification scheme has required revision to accommodate the anthropogenically altered landscape of Valley Forge.

Nevertheless, it is clear that Stereo Analyst offers advantages for vegetation and other types of mapping. Stereoscopic view and sharp zoom-in capabilities make photo interpretation straightforward. Because features are delineated directly into a GIS, Stereo Analyst cuts process time by 70% and avoids two steps that can introduce errors in conventional mapping methods (i.e., transfer to map base and digitizing). Perhaps most importantly, joint use of Orthobase and Stereo Analyst allows simultaneous orthophoto creation and GIS data collection; in contrast, the ArcMap approach requires finished orthophotos before features can be delineated. Ultimately, though, both monoscopic and stereoscopic methods have roles in vegetation mapping projects. The level of detail required for the project should determine which technique is most appropriate.

Annotation:

The Burgess Shale Fossils found in Yoho National Park are some of the oldest, most well-preserved, soft-bodies organisms ever found. These fossils provide valuable knowledge of Cambrian organisms and the origins of multicellular life. The construction of The Canadian Pacific Railway ultimately led to the discovery of these fossils by making the Kicking Horse Valley accessible to tourists, adventurers, and most importantly to our story, geologists. The railway can be seen as a vehicle of exploration, but for the First Nations peoples, it was a vehicle of exploitation that had harmed the natural environment and exploited their artifacts and resources.

EnviroScience, Inc. (EnviroScience) was contracted by the National Park Service (NPS) to design and implement a study plan to inventory the headwater stream resources within the Cuyahoga Valley National Park (CUVA). The parameters and expectations of the study are described in a Statement of Work (SOW) developed by NPS staff (NPS, 2021) to collect and analyze data to guide decision-making in the development of management plans to protect these resources within CUVA. The headwater stream inventory was comprised of three components to evaluate the resources as follows: 1. habitat and biological assessments to classify the streams in the context of the Ohio EPA Primary Headwater (PHW) stream classification system (Ohio EPA, 2020) and the beneficial aquatic life uses promulgated in Chapter 3745-1 of the Ohio Administrative Code (OAC), where applicable; 2. fluvial geomorphological assessments to determine stream channel types and to evaluate the potential and degree of streambank erosion associated with the assessment sites; and 3. development and testing of a visitor use impact assessment (VUIA) protocol for potential park-wide application to manage and protect stream resources in the context of public access. A total of 125 headwater stream sites were assessed to complete the inventory. The SOW identified eighty-three (83) of the sites designated as Primary sites by NPS. These sites were selected to document the condition of headwater streams with watershed areas of approximately 1.0 mi2. These sites were assessed using desktop methods and field reconnaissance. The final list of sites was modified as appropriate for approval by NPS. Forty-two (42) additional sites were proposed for assessment as Secondary sites following the assessment of Primary sites according to the SOW and study plan. These sites were selected to either provide additional data within Primary site watersheds or to expand coverage of the inventory within the park to target specific tributaries of interest. All inventoried sites were selected to meet the definition of Primary Headwater (PHW) streams as that term is defined in Ohio EPA headwater stream protocols. The identified locations were used to characterize the biological communities within the streams and to identify factors affecting the ecological integrity and water quality of the headwater streams within CUVA.

Sentinel wetlands at Cuyahoga Valley National Park (NP) comprise a set of twenty important management areas and reference sites. These wetlands are monitored more closely than other wetlands in the wetlands monitoring program and are the focus of the volunteer monitoring program for water levels. We used the Ohio Rapid Assessment Method (ORAM) to evaluate habitat in the sentinel wetlands. A total of 37 long-term sample plots have been established within these wetlands to monitor biological condition over time using vegetation as an indicator. Vegetation is intensively surveyed using the Vegetation Index of Biotic Integrity (VIBI), where all plant species within the plot are identiﬁed to the lowest taxonomic level possible (genus or species). Sample plots were surveyed twice from 2008 to 2018 and the vegetation data were evaluated using ﬁve metrics: VIBI, Floristic Quality Assessment Index (FQAI), percent sensitive plant species, percent invasive graminoids, and species richness. These metrics are discussed for each location. This report also highlights relevant land use histories, common native plant species, and invasive species of concern at each wetland. This is the ﬁrst report in a two-part series, designed to summarize the results from intensive vegetation surveys completed at sentinel wetlands in 2008–2018. Boston Mills, Virginia Kendall Lake, Stumpy Basin, Columbia, and Beaver Marsh are all in excellent condition at one or more plots. They have unique habitats with some specialized plant species. Fawn Pond is in good condition at most plots and scores very high in comparison to other wetlands within the riverine mainstem hydrogeomorphic class. Metric scores across mitigation wetlands were low. Two of the three wetlands (Brookside and Rockside) are not meeting the benchmarks originally established by the United States Army Corps of Engineers and Ohio Environmental Protection Agency. Krejci is still a young mitigation site and success will be determined over time. Park-supported invasive species control eﬀorts will be crucial for long-term success of these sites and future mitigation/restoration projects. The wetlands monitored because of proposed ecological restoration projects (Pleasant Valley, Stanford, and Fawn Pond) have extensive invasive plant communities. These restoration sites should be re-evaluated for their feasibility and potential success and given an order of prioritization relative to the newer list of restoration sites. Cuyahoga Valley NP has added many new areas to their list of potential wetland restoration sites after these areas were selected, and there may be better opportunities available based on restoration objectives. Restoration goals should be based on the park's desired future conditions, and mitigation goals of outside partners may not always be in line with those. The multiple VIBI plots dispersed throughout the large wetlands at Cuyahoga Valley NP detected and illuminated spatial patterns in condition. Many individual wetlands had a wide range of VIBI scores within their boundaries, sometimes reﬂecting localized disturbances, past modiﬁcations, and management actions. Most often, these large ﬂuctuations in condition were linked to local invasive plant infestations. These infestations appear to be the most obvious and widespread threat to wetland ecosystems within the park, but also the most controllable threat. Some sensitive species are still present in some of the lowest scoring plots, which indicates that invasive plant species control eﬀorts may pay oﬀ immediately with a resurgence of native communities. Invasive plant control at rare habitat sites would have large payoﬀs over time by protecting some of the park's most unique wetlands. Reference wetlands would also be good demonstration sites for park managers to try to maintain exemplary conditions through active management. Through this work, park managers can evaluate the feasibility, eﬀectiveness, and scalability of management practices required to maintain wetland condition.

Active sand dunes in Kobuk Valley National Park are a regionally rare and ecologically distinct landscape feature occurring within the northern boreal biome. The sand dunes harbor a rich diversity of plants, including several rare and disjunct species and the endemic Kobuk locoweed (Oxytropis kobukensis). Pollinators associated with these dune plants have not been studied in Kobuk Valley, despite their essential role in transporting pollen which many plants rely on for successful reproduction. In order to gain a better understanding of pollinator diversity and plant-pollinator associations in this unique ecosystem north of the Arctic Circle, we conducted surveys of bees (Hymenoptera: Anthophila) and syrphid flies (Diptera: Syrphidae) in several places along the Kobuk River and in two active dune areas, the Hunt River Dunes and the Great Kobuk Sand Dunes, in late June-early July of 2017 and 2019. We used active and passive collecting methods to sample pollinators at 21 different sites and along five walking transects, and we documented plant associations for net-collected specimens. In all, we collected 326 bees and 256 syrphid flies, representing 27 and 37 taxa, respectively. The most abundant and widespread species collected among syrphid flies were Lapposyrpus lapponicus and Eristalis obscura. For bees, three soil-nesting solitary species, Andrena barbilabris, Megachile circumcincta, and Osmia tarsata made up 60% of the total bee catch. Dryas integrifolia, a widespread plant on the dunes, hosted the highest number of bee and syrphid fly taxa (13 and 20, respectively). Bumble bees (Bombus) and megachilid bees (Megachile, Osmia) favored several plants in the Fabaceae family, while mining bees (Andrena) were abundant on Salix species (willow). A high diversity of syrphid flies were collected on the composite Packera ogotorukensis, and Salix species. Our collections indicate that the endemic Oxytropis kobukensis was primarily visited by the mason bee, Osmia tarsata (44% of all visitors) and the leafcutter bee, Megachile circumcincta (27%). Bumble bees (genus Bombus) made up another 13% of all visitors to this plant. Our study confirms that the active sand dunes in Kobuk Valley provide an ecologically unique habitat both for plants and their associated insect pollinators. For example, many of the solitary bees living in the dunes rely on deep sands for nesting and thus are limited in their distribution across Arctic and boreal landscapes.

Vegetation inventory and mapping is a process to document the composition, distribution and abundance of vegetation types across the landscape. The National Park Service’s (NPS) Inventory and Monitoring (I&M) program has determined vegetation inventory and mapping to be an important resource for parks; it is one of 12 baseline inventories of natural resources to be completed for all 270 national parks within the NPS I&M program. The Mojave Desert Network Inventory & Monitoring (MOJN I&M) began its process of vegetation inventory in 2009 for four park units as follows: Lake Mead National Recreation Area (LAKE), Mojave National Preserve (MOJA), Castle Mountains National Monument (CAMO), and Death Valley National Park (DEVA). Mapping is a multi-step and multi-year process involving skills and interactions of several parties, including NPS, with a field ecology team, a classification team, and a mapping team. This process allows for compiling existing vegetation data, collecting new data to fill in gaps, and analyzing the data to develop a classification that then informs the mapping. The final products of this process include a vegetation classification, ecological descriptions and field keys of the vegetation types, and geospatial vegetation maps based on the classification. In this report, we present the narrative and results of the sampling and classification effort. In three other associated reports (Evens et al. 2020a, 2020b, 2020c) are the ecological descriptions and field keys. The resulting products of the vegetation mapping efforts are, or will be, presented in separate reports: mapping at LAKE was completed in 2016, mapping at MOJA and CAMO will be completed in 2020, and mapping at DEVA will occur in 2021. The California Native Plant Society (CNPS) and NatureServe, the classification team, have completed the vegetation classification for these four park units, with field keys and descriptions of the vegetation types developed at the alliance level per the U.S. National Vegetation Classification (USNVC). We have compiled approximately 9,000 existing and new vegetation data records into digital databases in Microsoft Access. The resulting classification and descriptions include approximately 105 alliances and landform types, and over 240 associations. CNPS also has assisted the mapping teams during map reconnaissance visits, follow-up on interpreting vegetation patterns, and general support for the geospatial vegetation maps being produced. A variety of alliances and associations occur in the four park units. Per park, the classification represents approximately 50 alliances at LAKE, 65 at MOJA and CAMO, and 85 at DEVA. Several riparian alliances or associations that are somewhat rare (ranked globally as G3) include shrublands of Pluchea sericea, meadow associations with Distichlis spicata and Juncus cooperi, and woodland associations of Salix laevigata and Prosopis pubescens along playas, streams, and springs. Other rare to somewhat rare types (G2 to G3) include shrubland stands with Eriogonum heermannii, Buddleja utahensis, Mortonia utahensis, and Salvia funerea on rocky calcareous slopes that occur sporadically in LAKE to MOJA and DEVA. Types that are globally rare (G1) include the associations of Swallenia alexandrae on sand dunes and Hecastocleis shockleyi on rocky calcareous slopes in DEVA. Two USNVC vegetation groups hold the highest number of alliances: 1) Warm Semi-Desert Shrub & Herb Dry Wash & Colluvial Slope Group (G541) has nine alliances, and 2) Mojave Mid-Elevation Mixed Desert Scrub Group (G296) has thirteen alliances. These two groups contribute significantly to the diversity of vegetation along alluvial washes and mid-elevation transition zones.

Twenty important management areas (wetlands of management concern) and reference wetlands compose the sentinel wetlands at Cuyahoga Valley National Park. These wetlands are monitored more intensively than other wetlands in the program. This is the second report in a two-part series, designed to summarize the results from intensive vegetation surveys completed at sentinel wetlands from 2008 to 2018. The first report (Bingham and Young 2023) characterized the conditions in each wetland and provided baseline reference information for other reports and site-specific projects. In this report, we examine results from five selected metrics more closely within and across three natural wetlands of management concern groups (restoration wetlands, mitigation wetlands, and rare habitat wetlands) using the reference wetlands as overall benchmarks. We used the Ohio Rapid Assessment Method (ORAM) to evaluate habitat in the sentinel wetlands. In addition, a total of 37 long-term sample plots were established within these wetlands to monitor biological conditions over time using vegetation as an indicator. Multiple plots were located in larger wetland complexes to capture spatial differences in condition. Vegetation was intensively surveyed within the plots using the Vegetation Index of Biotic Integrity (VIBI), where all plant species are identified to the lowest taxonomic level possible (genus or species). The sample plots were surveyed twice, and the five evaluation metrics included the VIBI score, Floristic Quality Assessment Index (FQAI), percent sensitive plant species, percent invasive graminoids, and species richness. For the analysis, VIBI plot locations were rank ordered based on their 2018 scores, the range and average for each metric was examined across the wetlands of management concern groups and plotted against reference wetlands for comparison, and the two survey years (pre-2015 and 2018) were plotted against each other for substantial changes from the established baseline. Across the sample plot locations, VIBI scores ranged from a low of 7 (Stanford Run SF1) to a high of 91 (Columbia Run 554). The top scoring plots were at four reference wetlands (Stumpy Basin 526, Virginia Kendall Lake 241K, Columbia Run 554, and Boston Mills 683) and one rare habitat wetland (Beaver Marsh BM3). All of these plots fell within an excellent condition range in one or both survey years. They each have unique habitats with some specialized plant species. The majority (24) of the sentinel wetlands plots ranked within the poor or fair ranges. These include the three mitigation wetlands: Brookside 968, Rockside RS2, and Krejci, as well as all plots within the Pleasant Valley and Stanford Run wetlands. Most of the large wetlands had dramatic condition differences within their boundaries? effected by pollution sources, land-use modifications, and/or invasive species in some areas more than others. We documented these wide condition ranges at Fawn Pond, Virginia Kendall Lake, Beaver Marsh and Stumpy Basin, but the most pronounced within-wetland differences were at Virginia Kendall Lake, which had a 58-point difference between the highest and lowest scoring plot. Fawn Pond is in good condition at most plots and scored very high in comparison to other wetlands within the riverine mainstem hydrogeomorphic class. The average and range of most metric scores were notably different across the four different wetlands groups. Average values at rare habitat wetlands plots were similar to reference plots for VIBI and FQAI scores, percent invasive graminoids, and percent sensitive metrics. Krejci KR1 and Fawn Pond FP3 had unusually high percent cover of sensitive species (31.0% and 27.9%, respectively) for the mitigation and restoration groupings. However, average overall metric scores across the restoration and mitigation wetlands were generally very low, with Stanford Run being the lowest scoring restoration wetland and Brookside being the lowest scoring mitigation wetland. With restoration efforts completed, the expectation is that mitigation wetlands should be performing much higher. Two of the three mitigation wetlands sites are not meeting the mitigation benchmarks that were created for them by the US Army Corp of Engineers and the Ohio Environmental Protection Agency. Contractor reports state that the wetlands met the criteria within the first five years of establishment. However, upon release from monitoring and maintenance, invasive species have gradually re-established, which has led to condition deterioration over time, and lower metric scores. VIBI scores stayed the same or improved (only slightly in many cases) in the majority of plots (67.6%) between survey years. The Krecji mitigation wetlands had the largest improvement in VIBI scoring. Scores at six plots decreased by at least 10 points from the baseline survey. Two of the park?s most beloved wetlands, Beaver Marsh (at one location) and the Stumpy Basin reference plot, had the two most notable declines in VIBI scores. In 2018, 11 plots (29.7%) had greater than 25% invasive graminoid cover (e.g. cattail, common reed grass, reed canary grass) and 18 plots (48.7%) experienced an increase in invasive graminoid cover between survey years. A marked increase (>10% cover) in invasive graminoids was documented at eight locations (Rockside 1079RS2, Beaver Marsh BM5, Fawn Pond FP3 and FP4, Brookside 968, Stumpy Basin SB1, and two other Pleasant Valley plots: 1049 and 969). These trends are likely to continue, and biological conditions are expected to deteriorate at these wetlands in response. Regardless of invasive species increases, many of the wetlands showed remarkable resilience over the last decade with fairly stable VIBI categories.
