Vegetation communities serve as the foundation of habitat for many species, function as a carbon sink, produce oxygen, cycle nutrients and energy, improve water quality, and moderate flooding/erosion. Given the widespread anthropogenic influences in Southeast Coast Network parks and the importance of vegetation communities, quantifying trends in species diversity and forest regeneration is vital to understanding ecological processes and identifying stressors and their impacts. Evaluating trends in vegetation and environmental attributes provides measures for assessing the ecological integrity and sustainability of park’s terrestrial vegetation and identifies potential management activities on our park lands. The National Park Service Omnibus Management Act of 1998 and other reinforcing policies and regulations require park managers to establish baseline information and to provide information on the long-term trends in the condition of National Park System resources (Title II, Sec. 204). The data summarized herein is a tool to assist managers in fulfilling this mandate.

Vegetation communities are the primary drivers for a range of ecological processes and are integral to the proper function of park ecosystems. They serve as the foundation for food webs and wildlife habitat for many species, and function as a carbon sink, produce oxygen, cycle nutrients and energy through an ecosystem, influence the local climate, improve water quality, and moderate flooding and erosion. Given the widespread anthropogenic influences in Southeast Coast Network (SECN) parks and the importance of vegetation communities, quantifying trends in plant cover, frequency, diversity, and distribution is vital to understanding the ecological processes and identifying stressors and their impacts. Evaluating trends in plant cover, frequency, diversity and distribution provides measures for assessing the ecological integrity and sustainability of southeastern ecosystems, and identifying the need for specific management activities on our park lands. The National Park Service Omnibus Management Act of 1998 and other reinforcing policies and regulations require park managers to establish baseline information and to provide information on the long-term trends in the condition of National Park System resources (Title II, Sec. 204). The vegetation-community monitoring data summarized herein is a tool to assist park managers in fulfilling this mandate.

국립세종수목원을 방문하는 시민 안전 및 식물 생태 관리를 위한 기본 데이터를 2025년 사업 기간 동안 수집했습니다. 해당 수목원에서 전력, 지열에너지, 태양광, 지역난방 데이터를 수집하여 분석 및 통계 처리, 시설 제어를 통한 에너지 절감, 탄소배출량 관리, ESG 보고서 생성, NDVI를 통한 식물 생태 관리 등을 위해 활용하고 있습니다.

Ground-based monitoring for the vegetation composition and structure vital sign for the Southwest Alaska Network (SWAN), focuses on documenting trends in the structure, composition, and demography of selected late-successional vegetation classes in response to environmental changes across three elevation bands (0-450 m; >450-900 m; >900 m) within the three largest parks: Katmai (KATM), Kenai Fjords (KEFJ), and Lake Clark (LACL). SWAN employed a Generalized Random-Tesselation Stratified (GRTS) sampling design, which involved a two-stage sampling scheme to ensure safety and accessibility while establishing permanent plots in selected vegetation classes. In order to focus on long-term changes rather than successional dynamics, the monitoring targeted specific vegetation classes that are common, late-seral, and sensitive to environmental changes, while avoiding early-successional classes. The selected vegetation associations included low elevation interior spruce forests, mid-elevation white spruce woodlands, low and dwarf shrub communities, and alpine dwarf shrub-fellfield communities, reflecting a gradient from warm coastal to colder alpine environments. Selected monitoring plots were revisited at approximately 5 year intervals, during which point intercept, nested quadrat frequency, tree censuses, and other structural and environmental measurements were performed.

24 data containing .csv's comprising the main components of the SWAN Vegetation Monitoring Database plus another 24 .csv's describing the columns present on the main components of the SWAN Vegetation Monitoring Database.

These data were generated by the work of many different field crews (2011-2024) who visited each unit each year collecting information on the condition of selected resources (Vital Signs). The data collection was guided by established methods and detailed protocols including: paired (2) 50-m line-point intercept transects for abundance; 10, 1-m2 quadrats for species diversity; 314-m2 circular plots for small diameter woody species (shrubs, seedlings and saplings); and 314-m2 or 1000-m2 for trees greater than 2.5-cm at 1-meter above the ground (1-inch at breast-height). The purpose of these data is to inform park staff, planners, administrators, partners and the public with quantitative records of the composition and abundance of vegetation in National Park Units. These data were carefully collected using precise methods, careful documentation, and multiple quality control steps. Species names and codes were cross-referenced to the USDA “Plants” database authority. Rare and unknown species were collected and verified by staff of the Wyoming Natural Diversity Database, University of Wyoming. These data are working files used to guide and inform park managers who make decisions about conservation and management of habitats and resources of the park based on desired conditions of resources. These data are provided as one key piece of evidence to support management of vegetation, fuels and habitats. No claims are made, legal or otherwise, regarding the accuracy, precision and utility of these data.

The Northern Great Plains Network (NGPN) is part of the NPS Inventory and Monitoring Division (IMD). We provide scientific support, data and interpretation related to resource conditions in park units within the Network in support of the National Park Service Organic Act and the National Parks Omnibus Management Act (Title II, Section 204 – Inventory and Monitoring Program). The NGPN network includes 13 NPS units: Fort Union NHS, Theodore Roosevelt NP, Knife River Indian Villages NHS, Devils Tower NM, Jewel Cave NM, Mount Rushmore NMEM, Badlands NP, Wind Cave NP, Fort Laramie NHS, Agate Fossil Beds NM, Scotts Bluff NM, Missouri NRR, and Niobrara NSR.
