This map layer portrays the current routes used for conducting Breeding Bird Surveys in the lower 48 States.

This dataset was developed for the BLM Rapid Ecoregional Assessment for the Central Yukon and contains a database of descriptions of historic (inactive and closed) mines based on the Alaska Resource Data File (ARDF).
thumbnail
This data contains current and active placer mining activity and permits density by HUC10 units. It includes mining methods of suction dredging, placer mining and hardrock exploration permits, along with active mines from the Alaska Resource Data File.
thumbnail
This data contains historic (pre-2009) mining activity and permits density by HUC10 units. It includes mining methods of closed mining permits from ADNR, inactive mines from the Alaska Resource Data File, historic coal mines, and abandoned mine lands.

This dataset was provided to the Conservation Biology Institute by Dudek. Note, this dataset does not include data for all DRECP covered species.This layer includes species occurrence data derived from several different sources, including California Natural Diversity Database (CNDDB), Bureau of Land Management, California Department of Fish and Game, and California Avian Data Center data. Dudek used these data to model species distributions. The use of data from multiple sources collected at different times, spatial scales, and for different purposes can result in an unsystematic and spatially biased occurrence data set. Sampling effort is, as expected, far greater in the western Mojave Desert and the Imperial...
