There is often an inverse relationship between the diversity of a plant community and the invasibility of that community by non-native plants. Native herbivores that colonize novel plants may contribute to diversity–invasibility relationships by limiting the relative success of non-native plants. Here, we show that, in large collections of non-native oak trees at sites across the USA, non-native oaks introduced to regions with greater oak species richness accumulated greater leaf damage than in regions with low oak richness. Underlying this trend was the ability of herbivores to exploit non-native plants that were close relatives to their native host. In diverse oak communities, non-native trees were on average more closely related to native trees and received greater leaf damage than those in depauperate oak communities. Because insect herbivores colonize non-native plants that are similar to their native hosts, in communities with greater native plant diversity, non-natives experience greater herbivory.

Using Native Plants is a 120-min videotape that was developed as a result of a Cooperative Extension Partnership Programming Grant between the Univ. of Minnesota, Minnesota Extension Service and the Cooperative Extension–Univ. of Wisconsin-Extension. The content covers woodland wildflowers, prairie establishment and maintenance, landscaping lakeshores, and using native plants in traditional gardens settings.Video segments include: Eloise Butler Wildflower garden, Minneapolis, Minn.; Curtis Prairie, Madison, Wis.; Big Sandy Lake, Minn.; and the Minnesota Landscape Arboretum, Chanhassen. Developed originally as advanced Master Gardener training, the program was a national satellite broadcast on 29 Feb. 1996. It was viewed by at least nine states and more than 500 participants. Video production costs, including a 20-page participant's handout with extensive references and plant lists, were just under $13,000. A cost analysis, evaluation, sample of the participant's packet, pictures from the videotape and an order form will be presented. Copies of the tape and print packet may be obtained for $50 from Minnesota Extension Service, 1.800.876.8636, or Univ. of Wisconsin-Extension, at 1.608.262.3346.

To serve human needs, non-native species are selected based on an array of functional traits, which generally confer competitive advantages to these species in their recipient environments. Identifying non-obvious functional traits that indirectly inform human selection of non-natives to introduce into urban greenspaces is not yet part of common discussions in invasion biology. We tested whether functional traits integrated within a phylogenetic framework, may reveal those subtle criteria underlying the introduction of non-native plants into urban greenspaces. We found no differences in terms of functional traits between natives and non-natives. We also found no evidence that functional traits predict nectar production, irrespective of how nectar production was measured. Finally, we found that the mean sugar concentration of nectar per flower is evolutionarily shared both within closely related non-native plants as well as within close native plants. However, phylogenetically close species share similar intraspecific variation in mass of nectar sugar per flower, but this is true only for non-native plants, thus revealing a non-obvious selection criteria of non-native plants for urban greenspaces. Our results indicate that the phylogenetic patterns of intraspecific variation in mass of nectar sugar per flower is the major criterion distinguishing non-natives from native plants in urban greenspaces in Southern England.

Abstract Resource amendments commonly promote plant invasions, raising concerns over the potential consequences of nitrogen (N) deposition; however, it is unclear whether invaders will benefit from N deposition more than natives. Growth is among the most fundamental inherent traits of plants and thus good invaders may have superior growth advantages in response to resource amendments. We compared the growth and allocation between invasive and native plants in different N regimes including controls (ambient N concentrations). We found that invasive plants always grew much larger than native plants in varying N conditions, regardless of growth- or phylogeny-based analyses, and that the former allocated more biomass to shoots than the latter. Although N addition enhanced the growth of invasive plants, this enhancement did not increase with increasing N addition. Across invasive and native species, changes in shoot biomass allocation were positively correlated with changes in whole-plant biomass; and the slope of this relationship was greater in invasive plants than native plants. These findings suggest that enhanced shoot investment makes invasive plants retain a growth advantage in high N conditions relative to natives, and also highlight that future N deposition may increase the risks of plant invasions.

Resumo:
There is growing awareness about the value of preserving and restoring floral-rich habitats for the benefit of pollinators, especially native bees. The increasing demand for native plants in pollinator habitat restoration and other ecological landscaping applications, combined with the desire for more robust and predictable plant habits, have led to the selection and breeding of native cultivars. Yet, little is known about how these cultivated varieties differ from the native species in their ability to attract and support pollinators. I compared flower visitation by all insect pollinators to 12 native herbaceous plant species and 14 native cultivars in a replicated field experiment at two sites over two years. I classified insect pollinators during visual field observations into seven taxonomic and functional groups. I found seven native species to be visited significantly more frequently by all insect pollinators (combined) than their cultivars, four were visited equally, and one native cultivar was visited more frequently than the native species. Bees (both native and non-native) and moths/butterflies exhibited similar preferences, whereas flies showed no preference between the native species and the native cultivar. Our study shows that many insect pollinators prefer to forage on native species over cultivated varieties of the native species, but not always, and not exclusively. Some native cultivars may be comparable substitions for native species in pollinator habitat restoration projects, but all cultivars should be evaluated on an individual basis. Plant selection is integral to the value and success of pollinator habitat restorations, yet there is little consistency and overlap in pollinator planting recommendations and very little empirical data to support plant choice. Non peer-reviewed pollinator plant lists are widely available and are often region-specific, but they are typically based on anecdotal rather than empirical data and lack in specificity. To help close the gap between anecdotal and empirical data, and between practice and research, I reviewed the published literature on plant selection for pollinator habitat restoration. I explicitly reviewed and compared the value of native plant species, near-natives, non-natives and native cultivars. From there, I identified gaps in the literature that are most needed in practice and recommended basic strategies for practitioners to navigate plant lists and choose the best plants for a site's success.

Abstract The introduction of species to new locations leads to novel competitive interactions between resident native and newly-arriving non-native species. The nature of these competitive interactions can influence the suitability of the environment for the survival, reproduction and spread of non-native plant species, and the impact those species have on native plant communities. Indeed, the large literature on competition among plants reflects its importance in shaping the composition of plant communities, including the invasion success of non-native species. While competition and invasion theory have historically developed in parallel, the increasing recognition of the synergism between the two themes has led to new insights into how non-native plant species invade native plant communities, and the impacts they have on those plant communities. This chapter provides an entry point into the aspects of competition theory that can help explain the success, dominance and impacts of invasive species. It focuses on resource competition, which arises wherever the resources necessary for establishment, survival, reproduction and spread are in limited supply. It highlights key hypotheses developed in invasion biology that relate to ideas of competition, outlines biotic and abiotic factors that influence the strength of competition and species' relative competitive abilities, and describes when and how competition between non-native and native plant species can influence invasion outcomes. Understanding the processes that influence the strength of competition between non-native and native plant species is a necessary step towards understanding the causes and consequences of biological invasions.

In the study, it is aimed to create breeding lines of thyme (Thymbra spicata L.), which is important both culturally and economically, by selecting a single plant among the plants grown in different regions in Hatay. For this purpose, a genetic pool was created for Thymbra spicata L. plant in the plant samples taken from the locations where the plants are densely grown, and these plants were examined in terms of leaf characteristics, number of oil glands per unit area, oil gud size and essential oil components. Plants were propagated and preserved with cuttings taken from these single plants. In this study, which includes the pre-selection stage, 213 plants from 68 different locations were determined in the province of Hatay. The essential oil ratios of the plants varied between 0.70% and 3.90% and showed a wide variation. The rate of carvacrol, which is the main component of the essential oil of the thyme plant, was between 28.12% and 78.48%. Plants with code number Z14, Z3, Z25, Z38, Z77, Z104, Z35 and Z43 with an essential oil ratio of 3.5% and above and plants with code number Z167, Z165 and Z64 with a high carvacrol ratio were selected to be used in future breeding studies.

Poultry meat and eggs are considered as one of the most popular food items all over the world due to their content of high quality nutrients including protein, lipids, vitamins, and minerals. During the past decade, many countries have increased their commercial production of these essential products to meet the increased demand by consumers, especially with the increasing populations all over the world. However, there is an urgent need to ensure sustainable poultry production for the local consumer. Using native plants in poultry feed is an innovative approach that can improve food security and promote sustainability in the poultry industry. Native plants have adapted to local conditions, are often more resistant to pests and diseases, and require less water and fertilizers compared to non-native plants. Additionally, incorporating native plants into poultry feed can diversify the diet of the birds, leading to better health and nutrition. The current paper focuses on the potential use of nine species of native plants in the state of Kuwait that can be used in poultry feed to enhance the local food security and sustainability. This work is under the umbrella of the Government Initiative (GI) Project (P-KISR-17) �Establishment of Model Farm Utilizing Modern Technologies for Local Production� (subtask 3.1: Poultry production). The goal of this GI is to reduce water and food vulnerability in Kuwait.

This study evaluated mowing regimes, changes in native and non-native plant communities, deer presence in the research plots,and public perception of various management practices on ROWs. No significant difference was found in the height of vegetation 3 weeks after each mowing between research plots mowed 4 times per year and plots mowed only once per year in uplands or lowlands. Native plants increased in plots mowed once per year and deer preferred the frequently mowed plots where clovers and vetches had been seeded. Increasing the carrying capacity of the lowlands with more extensive plantings of clover and vetch may attract deer, thus encouraging them to browse and use the underpasses beneath bridges and making the ROWs safer. The public survey found strong support for wildflowers on ROWs and a distaste for litter. Further, respondents would tolerate a less manicured ROW if it saved money, made the roads safer, and hid litter.

Assessing the genetic diversity of Nymphoides peltata in the native and adventive range using microsatellite markers.

Nymphoides peltata (yellow floatingheart), native to Eurasia, is an invasive plant in the USA, where it grows in relatively isolated but widespread populations. The species is capable of sexual reproduction by seed and asexual reproduction through fragmentation. Although N. peltata is recognized as a noxious weed, little is known about its geographic region of origin or its dispersal mechanisms and relative amount of genetic variation in its adventive range. We conducted a genetic analysis of N. peltata by studying 68 localities across the native range and 47 localities in the adventive range, using microsatellite markers to determine genetic variability within and among populations, and to infer regions in the native range from which invasive plants originated. A large number of sites in the USA were genetically identical to one another, and there were two predominant multilocus allele phenotypes that were distributed in the northern and southern latitudes, respectively. Additional USA sites were similar to one of the predominant genetic profiles, with greater genetic diversity in southern populations. The genetically identical sites are consistent with asexual spread, potentially via anthropogenic mechanisms. Plants across the USA range were observed to produce viable seeds, and some genetic variation could be explained by sexual reproduction. All USA plants were more similar to plants in Europe than they were to plants in Asia, indicating that the plants likely were introduced originally from Europe. The existence of two genetic clusters and their similarity to plants in different parts of Europe constitute evidence for at least two N. peltata introductions into the USA.

This report presents the results of vegetation monitoring efforts in 2020 at Fort Laramie National Historic Site (FOLA) by the Northern Great Plains Inventory and Monitoring Network (NGPN) and the United States Geological Survey (USGS). This was the tenth year of combined monitoring efforts. Crew members from USGS visited 9 long-term monitoring plots to collect data on the plant communities at FOLA. This work is part of a long-term monitoring effort designed to provide a better understanding of the condition of the vegetation community at FOLA and how it changes over time. USGS staff measured species richness, herb-layer height, native and non-native species abundance, ground cover, and site disturbance at each of the nine plots. In plots where woody species were present, tree regeneration, tall shrub density, tree density, and woody fuel loads were also measured. Data collection at seven plots was incomplete, where only point-intercept, site disturbance, and invasive species presence data were collected, while in two plots the previously listed protocols as well as the quadrat protocol were performed. In 2020, the monitoring crews identified 44 unique plant species in 9 monitoring plots. Of those species, 19 were exotic species. In a majority of plots (5 of 9), there was a greater percent of native species cover compared to exotic species cover. However, exotic plants were found at every plot in FOLA. No rare species were observed during our surveys

The Indiana Dunes (comprised of 15 geographic units (see Figure 1) which include Indiana Dunes National Park, Dunes State Park, and adjacent Shirley Heinze Land Trust properties) are remarkable in the Midwest and Great Lakes region for the vascular plant diversity, with an astounding 1,212 native plant species in an area of approximately 16,000 acres! This high plant diversity is the result of the interactions among postglacial migrations, the variety of soil substrates, moisture conditions, topography, successional gradients, ?re regimes, proximity to Lake Michigan, and light levels. This richness is all the more signi?cant given the past human alterations of the landscape resulting from logging; conversion to agriculture; construction of transportation corridors, industrial sites, and residential communities; ?re suppression; land abandonment; and exotic species invasions. Despite these impacts, multiple natural areas supporting native vegetation persist. Thus, each of the 15 units of the Indiana Dunes presents up to eight subunits varying in human disturbance and consequently in ?oristic richness. Of the most signi?cant units of the park in terms of number of native species, Cowles Dunes and the Dunes State Park stand out from all the other units, with 786 and 686 native species, respectively. The next highest ranked units for numbers of native species include Keiser (630), Furnessville (574), Miller Woods (551), and Hoosier Prairie (542). The unit with lowest plant richness is Heron Rookery (220), with increasing richness in progression from Calumet Prairie (320), Hobart Prairie Grove (368), to Pinhook Bog (380). Signi?cant natural areas, retaining native vegetation composition and structure, include Cowles Bog (Cowles Dunes Unit), Howes Prairie (Cowles Dunes), Dunes Nature Preserve (Dunes State Park), Dunes Prairie Nature Preserve (Dunes State Park), Pinhook Bog, Furnessville Woods (Furnessville), Miller Woods, Inland Marsh, and Mnoke Prairie (Bailly). Wilhelm (1990) recorded a total of 1,131 native plant species for the ?ora of the Indiana Dunes. This was similar to the 1,132 species recorded by the National Park Service (2014) for the Indiana Dunes. Based on the nomenclature of Swink and Wilhelm (1994), Indiana Dunes National Park has 1,206 native plant species. If we include native varieties and hybrids, the total increases to 1,244 taxa. Based on the nomenclature used for this report?the Flora of North America (FNA 2022), and the Integrated Taxonomic Information System (ITIS 2022)?Indiana Dunes National Park houses 1,206 native vascular plant species. As of this writing (2020), the Indiana Dunes is home to 37% of the species of conservation concern in Indiana (241 out of 624 Indiana-listed species): state extirpated = 10 species, state endangered = 75, and state threatened = 100. Thus, 4% of the state-listed species in the Indiana Dunes are extirpated, 31% endangered, and 41% threatened. Watch list and rare categories have been eliminated. Twenty-nine species once documented from the Indiana Dunes may be extirpated because they have not been seen since 2001. Eleven have not been seen since 1930 and 15 since 1978. If we exclude these species, then there would be a total of 1,183 species native to the Indiana Dunes. Many of these are cryptic in their life history or diminutive, and thus are di?cult to ?nd. Looking at the growth form of native plants, <1% (nine species) are clubmosses, 3% (37) are ferns, 8% (297) are grasses and sedges, 56% (682) are forbs or herbs, 1% (16) are herbaceous vines, <1% (7) are subshrubs (woody plants of herbaceous stature), 5% (60) are shrubs, 1% (11) are lianas (woody vines), and 8% (93) are trees. Of the 332 exotic species (species introduced from outside North America), 65% (219 species) are forbs such as garlic mustard (Alliaria petiolata), 15% (50 species) are graminoids such as phragmites (Phragmites australis ssp. australis), 2% (seven species) are vines such as ?eld bindweed (Convulvulus arvensis), <1% (two species) are subshrubs such as Japanese pachysandra (Pachysandra terminalis), 8% (28 species) are shrubs such as Asian bush honeysuckle (Lonicera spp.), 1% (three species) are lianas such as oriental bittersweet (Celastrus orbiculatus), and 8% (23 species) are trees such as tree of heaven (Ailanthus altissimus). Of the 85 adventive species, native species that have invaded from elsewhere in North America, 14% (11 species) are graminoids such as broom sedge (Andropogon virginicus), 57% (48 species) are forbs such as fall phlox (Phlox paniculata), 5% (six species) are shrubs such as Carolina allspice (Calycanthus floridus), 3% (two species) are subshrubs such as holly leaved barberry (Berberis repens), 1% (one species) is a liana (trumpet creeper (Campsis radicans), 3% two species) are herbaceous vines such as tall morning glory (Ipomoea purpurea), and 17% (15 species) are trees such as American holly (Ilex opaca). A total of 436 species were found to be ?special? based on political rankings (federal and state-listed threatened and endangered species), species with charismatic ?owers, and those that are locally rare.

Baseline information on canopy regeneration and plant community composition is needed in order to better understand white-tailed deer browsing impacts at First State National Historical Park (FRST). In 2021, the Pennsylvania Natural Heritage Program (PNHP) established 20 permanent vegetation monitoring plots following methods developed by the NPS Eastern Rivers and Mountains Network (ERMN) to assess and monitor trends in vegetation (Perles et al. 2014b; Perles et al. 2017). These protocols provided an efficient method of assessing the current status of native and non-native vegetation and deer browsing impact. This report documents the methodology used to quantify the vegetative composition of natural areas at FRST and provides a summary of the data collected in the first year of monitoring. This first year’s activities (2021) included the initial baseline vegetation assessment and summary of results from the baseline data analysis. A variety of metrics used to assess the impact of deer browsing on the vegetation were calculated and are presented. A second survey is proposed for 2024. PNHP used the NPS ERMN database and analysis methods (Perles et al. 2014b) to summarize the condition in year 1 (2021). In year 4 (2024), PNHP will investigate changes in the condition of browse-sensitive understory plants and tree seedlings. Plots occurred in a variety of settings, ranging from younger successional communities to more mature forest stands. Seventy-five percent (75%) of the plots occurred in Mature or Late Successional forests. Disturbances and stressors, such as deer browsing can strongly influence future forest structure as open woodlands mature. A large population of white-tailed deer may severely impact succession from the open woodlands towards closed canopy forest. In closed canopy, later successional forests, a large deer population may inhibit canopy tree recruitment leading to regeneration failure. Given that FRST managers desire to maintain the landscape as forest, it is important to maintain an adequate number of seedlings and saplings of tree species to ensure the persistence of canopy of native tree species as Mature and Late Successional Forests continue to age. The 20 permanent sampling plots occurred within 5 plant communities described by Ebert (2016) and were classified using agglomerative hierarchical clustering (HAC analysis) and indicator species analysis. The most common plant communities within the group of sampling plots were the Mixed oak – beech forest and Mesic mixed tulip – oak-hickory-beech forest. The remaining plots were found in successional Tuliptree woodland, Successional woodland, and Thicket types. All plots were assigned to these types described in Ebert (2016) and crosswalked to the National Vegetation Classification (USNVC). A total of 128 plant species were recorded from the 20 plots at FRST. Eighteen (18) species were found in over ½ of the plots surveyed, of which eight (8) were non-native. In all, 29 plants occurring in the plots (23% of total species richness) were considered introduced (non-native). Non-native plant cover ranged from 0–98% as measured in the monitoring plot quadrats. Indicators of deer browsing varied by plant community type at FRST. In general, the drier Mixed oak – beech forests showed substantially greater impact of deer browsing and fewer seedlings of canopy species in the understory. FRST monitoring protocols focus on a few plant species considered as preferred food for white-tailed deer. Sustained browsing may be affecting long-term viability of these species within the parks. Based on the status of these regeneration metrics in FRST, we suggest that the forest in FRST are in imminent regeneration failure. We define imminent failure as parks that are experiencing severe regeneration failure and are at risk of forest loss due to very low seedling and sapling abundance, as well as species mismatches between canopy and regeneration layers. Given the poor regeneration of canopy species across all community types at FRST, managers should seek opportunities to conduct adaptive management in the park’s forests, especially mixed oak – beech forest, to experiment with and monitor the effects of fire, browse exclosures, and canopy thinning to encourage native canopy tree regeneration.
