Wind-driven seed dispersal differentially promotes seed trapping and retention across alpine plants
Forage Resources in Warming and Removal Plots, Almont, CO, 2019
This is data collected to explore the impacts of warming and dominant species removal on the quantity and quality of plants for cattle foraging. The data were collected from the Colorado low elevation site (Almont) of the Warming and Removal in Mountains experiment which examines the direct and indi

Meteorological and Soil Data from Ecohydrology Sensor Towers at Pump House and Snodgrass Mountain in East River Watershed, Colorado, 2019-2025
This data package includes hourly meteorological and soil sensor data at eight ecohydrology monitoring sites in East River Watershed, Colorado as part of the Watershed Function Scientific Focus Area (WFSFA) research led by Lawrence Berkeley National Lab (LBNL). Four field sites were located on the h
Herbarium specimens reliably track plant phenological responses to climate change in understudied montane biomes
File: Peng_et_al._20206.zip Description: There are three folders here. The Data folder contains the raw specimen phenology data and the RMBL phenology data. The Analyses folder contains the data frames used to build the linear mixed-effects models. The Codes folder contains R codes

CHESS 2025: Field-collected vegetation attributes and site photos
This dataset represents field observations of vegetation samples collected as part of the Colorado Headwaters Ecological Spectroscopy Study (CHESS) during June and July of 2025. Samples were collected in the field using tablet computers and digital forms, with target data differing by sample type (i
CHESS 2025: Leaf Area Index (LAI) for meadow, shrub, tree, and understory vegetation
This dataset contains Leaf Area Index (LAI) measurements made as part of the Colorado Headwaters Ecological Spectroscopy Study (CHESS) during June and July of 2025. Data were collected in the Upper Gunnison Basin, Colorado, across three study domains: the Upper East River (CRBU), Almont Triangle (AL
Soil signals of key mechanisms driving greater protection of organic carbon under aspen compared to spruce forests in a North American montane ecosystem
Social security: individuals in socially reciprocal groups may perceive security from predators
Alpine plants of Mt. Baldy: modeling phenology and documenting biodiversity
Alpine ecosystems are disassembling and reassembling due to climate change. The phenology of alpine plants has shifted, but empirical evidence for how spatial clustering patterns could impact this shift is lacking. This study investigated the phenology of spatially clustered versus isolated alpine p
Moss and vascular plant cover across elevational gradients in a changing alpine climate
Mosses are foundational members of alpine plant communities but are often excluded from vegetation monitoring. In this study, I surveyed moss and vascular plant cover across five alpine ridges near Gothic, Colorado to understand how environmental variables shape moss abundance. I analyzed vegetation
Alpine plant spatial clumping modifies leaf surface temperature
Alpine plant communities are particularly susceptible to the impacts of climate change, which makes predicting how these communities will respond important for their conservation. This can be better predicted by understanding how the communities assemble, which is highly influenced by species intera
The effect of changing floral density on pollinator networks in a subalpine meadow environment
Plant-pollinator networks shape the populations of flowering plants across the world. Ecosystems face increasing challenges that decrease floral density and threaten to restructure plant-pollinator networks. The responses of these networks will play a critical role in the fates of plant species, bec
The effect of human pressure on the flight initiation of montane breeding birds throughout the summer breeding season
The summer is a peak tourism season in the Colorado Rocky Mountains, but is also the breeding season for many montane bird species, resulting in an increase in bird-human interactions and coexistence. I measured the effect that human activity has on the flight initiation behavior of two montane bird
Vegetation structure effect on bird foraging behavior across the summer season in montane wet-meadows
Mountain White-crowned Sparrows and Wilson’s Warblers rely on foraging microhabitats in montane wet meadows during the breeding season to find food for themselves and their offspring. The microhabitats are comprised of vegetation, which can be food itself, but it can also be a substrate for inverteb

Effects of experimental warming on floral scent, display and rewards in two subalpine herbs
Our results suggest that floral traits can show different levels of plasticity to temperature changes in subalpine environments, with potential effects on animal behaviours that help or hinder plant reproduction. They also illustrate the need for more long-term field warming studies, as shown by res
Abiotic influences on continuous conifer forest structure across a subalpine watershed
Understanding the abiotic drivers of high-elevation forest physiognomy is essential for forecasting how mountain ecosystems will respond to emerging environmental pressures. Most prior studies of these relationships have relied on small samples of the full landscape, resulting in limited power to de
Woodsy Owl on Hiking and Backpacking
Before your hike, study maps of the area, get permits if necessary, and learn the terrain. Be familiar with all options-- time, alternative routes, and weather. Keep in mind the shorter daylight hours of fall and winter. LIMIT THE SIZE OF YOUR GROUP Limit your group to a size a leader can safely han
