Climate Distance Mapper

Climate Distance Mapper

Climate Distance Mapper is a spatial decision-support tool designed to help land managers match seed sources with restoration sites. Plant populations are commonly adapted to local climate gradients and frequently exhibit a home-site advantage.

Mangrove Elevation and Species' Responses to Sea-level Rise Across Pohnpei, Federated States of Micronesia

Future sea-level rise poses a risk to mangrove forests. To better understand potential vulnerability, we developed a new numerical model of soil elevation for mangrove forests. We used the model to generate projections of elevation and mangrove forest composition change under four sea-level rise scenarios through 2100 (37, 52, 67, and 117 cm by 2100).

Survey data for chaparral vegetation in masticated fuel treatments on the four southern California national forests (2011-2012)

Mechanical fuel treatments are a primary pre-fire strategy for potentially mitigating the threat of wildland fire, yet there is limited information on how they impact shrubland ecosystems.

Mercury concentrations in western gulls along the west coast, USA, 2015-2017

We investigated whether foraging habitat, sex, or fidelity to a foraging area effected blood mercury concentrations in western gulls (Larus occidentalis) from three colonies on the west coast of the United States. Dataset includes total mercury concentrations in western gulls from three colony locations and associated foraging habitat of individual gulls.

Post-fire conifer regeneration observations for National Forest land in California (2009 - 2017)

This data consists of presence/absence observations for post-fire conifer regeneration. The data also includes estimates of plot-level topography (slope, aspect), relativized differenced normalized burn ratio (RdNBR), post-fire climate, live basal area, and seed rain.

Species observations from pitfall trap arrays, species pool matrices, and patch locations in southern California from 1995-2015

Observations (reduced to detected/not detected) of 45 vertebrate species (seven mammals, seven amphibians, and 31 reptiles) across Southern California pitfall sampling projects conducted between 1995 through 2015. Habitat patch locations of every pitfall sampling project presented in a shapefile.

Characteristics of Sites Sampled for eDNA of Amphibians in Mendocino County, California, 2016

Stream-obligate amphibians are important indicators of ecosystem health in the Pacific Northwest, but distributional information to improve forest management is lacking in many regions.

Western sandpiper diet composition in south San Francisco Bay, CA

Diet composition can be influenced by age- and sex-related factors including an individual's morphology, social status, and acquired skills; however, specialization may only be necessary when competition is intensified by high population densities or increased energetic demands.

Code and Data to fit an Integrated Population Model for the Foothill Yellow-legged Frog, Rana boylii, in northern California

These data include egg mass counts and adult capture-mark-recapture histories for Foothill Yellow-legged frogs (Rana boylii) at two streams in northern California. Data were collected from the South Fork Eel River and its tributary, Fox Creek, from 1993-2019. Data from Hurdygurdy Creek were collected from 2002-2008.

Dixie Valley Toad Radio Telemetry Data from Churchill County, Nevada, 2018-2019

This U.S. Geological Survey data release includes tabular data collected to characterize the habitat and movement of Dixie Valley toads. Data were collected in Dixie Valley, Nevada, in autumn 2018 and spring 2019.

Seed and Associated Tree Data from Long Term Research Plots in Sequoia and Yosemite national parks

This dataset was used as part of a continent-wide analysis of tree fecundity and its association with climate and tree size. This dataset consists of: plotinfo.csv, which contains basic attribute information for the field plots where the data were collected; seeddata.csv, which contains the data for seeds collected (how many, what type, etc.); trapxycoord.
