Pearl Conducts Tree Survival Surveys

The MRBA team recently went out into the watershed to conduct tree survival surveys. The surveys were being done on trees planted by MRBA in previous springs. Sarah, Ellen, Ruby, Aaron, and Pearl visited four sites across two days.

These tree survival surveys are important because they reveal how well the tress that have planted are doing and where more trees need to be planted in the future.

During the surveys, the team assess the number of trees that have survived and give each tree a vigor score of 1-3 that reflects their current health. One being the least healthy and 3 being the healthiest.

The team visited two sites in Lowell, one in North Troy, and one in Enosburgh. On some sites every tree was counted, but on sites where more trees were planted, transects were conducted.

Transects run perpendicular to the stream, and should extend a few feet beyond the extent of the planted trees. The first transect should be at least 50 feet from the project upstream boundary. If possible, transects should be at least 200 feet apart and equally distributed

throughout the project area. It is recommended that you set up the transects during the initial planting. If you are able to set up transects during initial planting, make sure to count and record the planted stems in each transect.

Set up transects. Pound a stake at each end of the transect: one stake near the stream edge and one stake near the outside edge of the planting. Number each transect (1, 2, 3, etc) and write the number on the stake. Run a tape measure between the two stakes in each transect to record the transect length.

When conducting tree survival surveys be sure to wear appropriate clothing like hats, boots, and pants. It is important to hydrate, and bring all the necessary materials such as tape measures, stakes, and a mallet.

Pearl had a great time running around fields and even taking a dip in the river! It is always great to be in the field as a team, getting stuff done and enjoying the Watershed!
