The indicator measures the percentage of land cover dominated by meadow (wet and dry variants) and wetland vegetation in the Tahoe Region in relation to the total amount of undisturbed vegetation. The relative proportion of meadows and wetlands is important because the areas provide flood attenuation, wildlife habitat, ground water recharge, water filtration, and aesthetic and recreation values. The primary factors influencing the extent of meadow and wetland vegetation are the geomorphic setting and the seasonal or permanent presence of surface groundwater, subsurface groundwater, and/or saturated soil. Urbanization has altered the movement of water through some meadow and wetland systems through impoundments, water rerouting, and the creation of impervious surface such as paved roads and building footprints. TRPA has adopted policies and ordinances designed to promote the conservation and protection of existing meadow and wetland vegetation types. In addition, Environmental Improvement Program partners implement meadow and wetland restoration and enhancement projects, which have  increased in wetland and meadow vegetation acreage. Programs such as TRPA’s transfer of development rights program provide additional incentives for moving development rights out of environmentally sensitive areas.
