Vegetation map for the Hakalau Forest Unit and adjacent lands, Hakalau Forest National Wildlife Refuge, Island of Hawaii. Derived from imagery taken in 2010 - 2014. This data layer identifies the boundaries of the mapped plant communities for the vegetation map of the Hakalau Forest National Wildlife Refuge Hakalau Forest Unit and adjacent lands, island of Hawaii. Tags: Hakalau Forest National Wildlife Refuge, Hawaii, plant communities, vegetation Wetland plants of the Yellowknife Study Area, 1961-1962 The Yellowknife Study Area (YSA),Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-square km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made...

At each site, 70, 2.5 x 2.5 m plots were assigned randomly to nitrogen-alone or nitrogen+water addition treatments (or no treatment for the control). Treatments were applied and data collected 2010-2013. The dataset includes six tables: (1) experimental treatments by plot and year; (2) plant and soil metrics analyzed in the larger work; (3) plant tissue and soil total carbon and nitrogen raw data; (4) plant biomass raw data; (5) canopy and ground cover raw data; and (6) canopy and ground cover codes.

An objective of our study was that species within plant communities have unique climate suitability signatures and forecast changes in climatic suitability will not be uniform within the species respective communities or among species within the community. The climate suitability spatial models were developed under a modern baseline (1960-90) and future climate scenario (2041-2060) using Maxent and WorldClim temperature and precipitation variables.

Tags: Hakalau Forest National Wildlife Refuge, Hawaii, USGS Science Data Catalog (SDC), plant communities, vegetation Metrics of plant community in C3 and Marsh Creek experimental blocks, Seney National Wildlife Refuge, Michigan, 2006-2010 Plant cover data were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing seasons before the burn (2006, 16 blocks; 2007, 15 blocks) and two-three growing seasons (2008, 2009, and 2010; 13 blocks) after burning; the unburned plot of each pair served as the control, and the burned plot of each pair the treatment.

Objectives of our study were to (1) describe how climate change will alter the biomass and composition of key plant functional types; (2) quantify the impacts of climate change on future functional type biomass and composition along climatic gradients; (3) identify if and which geographic locations will be relatively unaffected by climate change while others experience large effects; and (4) determine if there is consistency in climate change impacts on plant communities among...

An objective of our study was that species within plant communities have unique climate suitability signatures and forecast changes in climatic suitability will not be uniform within the species respective communities or among species within the community. We developed these spatial models where climate exposure is represented as a composite score of the climate exposure of characteristic plants for each community.
