tree with frost crackWisconsin winters with subzero weather can create problems for our trees. Frost cracks are one of those problems we’re seeing an uptick of lately. These longitudinal openings can run the entire length of the trunk, often extend deep into the wood, and permanently damage a tree. In wintertime, the tree may even look like it’s splitting in half! Then warmer weather comes, and the crack seems to close, repeating this process annually. Over time, frost cracks may even develop a raised area where callus tissue develops in an attempt to close over the wound, only to reopen again next winter.

Urban Tree Canopy (UTC) assessments using aerial or satellite imagery have been one of the primary ways people estimate the extent of urban forests across an area of interest, whether it be a single park, a streetscape or a whole community.

Two recently released UTC resources are ready for use by Wisconsin communities and urban forestry practitioners. The first, TreeCanopy.us, is a mapping application that shows UTC and other land cover in urban areas across the country for 2017 and 2022. It also shows changes in canopy cover between those five years. Continue reading “New Tree Canopy Resources Released” →

Winter Tree ID

Posted on by janness

How do you learn to identify trees in the middle of a Wisconsin winter when most of the leaves are on the ground?

LEAF’s Winter Tree Key follows the dichotomous process of our regular tree key but uses detailed illustrations of buds, twigs and features other than leaves for identification. The key also includes an illustrated glossary defining the specific vocabulary involved in this process. Winter tree identification can be a bit more demanding. Continue reading “Winter Tree ID” →
