Excellent Data Analysis Enables Enduring Solutions

We statistically analyze data acquired from the field and interpret it for managers and decision-makers. We recommend sampling designs that are cost-effective and efficient at getting to the key, early-warning indicators of ecological change.

 

San Clemente Island Vegetation Condition and Trend Analysis

In 1993, Tierra Data, under contract with the U.S. Navy, implemented a long-term vegetation monitoring program for San Clemente Island. We documented dynamic changes taking place in the biotic and abiotic environment following the removal of feral goats. We established and monitored more than 100 vegetation plots on San Clemente Island, sampling intermittently for close to 20 years. A variety of vegetation parameters were collected and analyzed. This trend analysis aids in conserving a full range of natural habitat diversity and species, native to this biologically distinctive island, within context of the military mission.
