Eastern Gulf of Mexico States Most Pervasive and Severe Disturbances Figure

from the 2015 National Fish Habitat Assessment

Summary

Most severe disturbances in the Eastern Gulf of Mexico States associated with stream reaches being scored as having high or very high risk of habitat degradation. Disturbances are grouped into super categories (fragmentation by dams; nutrient and sediment pollution; human population; road length and crossings; water withdrawals; urban land use; agricultural land use; mines and impervious surface cover) within the four spatial scales (local catchment, network catchment, local buffer, and network buffer). Only disturbance groups that have greater than 5% of stream length in a given category are represented in this figure. Note that not all disturbance categories are available for each spatial scale; buffers have only urban land use, [...]
