Graph of land cover data

This chart displays annual land cover and rainfall specifically for LTDL treatment polygon areas. Information from these charts can help resource managers understand the long-term vegetation trends from past treatments, alongside the context of annual precipitation and other fire and treatment disturbances.  This example is from a post-wildfire treatment. The fire and treatment occurred in 2007, which is delineated with a dashed red line for years of fire and a black line for the year of treatment. Before the fire, the area was dominated by shrubs (totaling ~30%), which plummeted to near zero immediately after the fire event. In the wake of the fire, bare ground briefly spiked to over 50% before being replaced by a surge in herbaceous plant cover, which remained the dominant cover (near 40%). While total shrub cover has steadily recovered to about 22%, it remains below pre-fire levels, and precipitation (shown as background bars) continues to fluctuate annually, influencing these recovery trends.
