It takes more than a village to foster healthy forests. More than a township, a city and a county, too. Sometimes, even more than a state.

That’s why the Great Lakes Basin Forest Health Cooperative (GLB FHC) was formed four years ago by Holden Arboretum in Ohio and the U.S. Department of Agriculture Forest Service.

Geographically, the group’s region encompasses an area from New Jersey to Wisconsin. The Wisconsin Department of Natural Resources (DNR) is an active member.

The trees on school properties mirror those of the surrounding urban forest in composition but not in coverage.

That is one initial takeaway from an i-Tree Eco project on Milwaukee Public School (MPS) properties conducted by Wisconsin Department of Natural Resources (DNR) Urban Forestry interns Priscilla Loh and Taylor Colman this summer.

A Busy Summer For Urban Forestry Interns

Every year, the summer ends faster than one could pronounce Liquidambar styraciflua, and this year was no exception. Hopefully, while you are trying to recall proper Latin pronunciations, your summer is still filled with enjoyable, productive or illuminating activities. That was certainly the case for the DNR Urban Forestry summer internship program. This summer, staff worked with Southern University students Taylor Colman and Priscilla Loh on a variety of different data collection projects, filling the internship’s eight weeks with species identification, tree mensuration and tree health assessments.

Retracted: Study Shows Drought Harms Wetter Forests Most

Note:

The original version of this Forest Health News article has been removed because the journal article in Science magazine that was referenced has been retracted by its authors due to a mathematical error. The journal authors reran their analysis and although many results remained unchanged, the statistical significance of some conclusions, and the results of some robustness tests, did change. It is unclear to what degree these errors affected observations in the Forest Health News article, so that article was removed. More information is available here.

New-And-Improved USDA Plant Hardiness Zone Map

Posted on by janness

The USDA Plant Hardiness Zone Map is the standard by which gardeners and growers can determine which perennial plants are most likely to thrive in a given location. The map is based on the average annual extreme minimum winter temperature, displayed as 10-degree Fahrenheit zones and 5-degree Fahrenheit half zones.

WI USDA Plant Zone MapThirty years of data was reviewed by a group of horticultural, botanical and climatological experts for the latest USDA Plant Hardiness Zone Map revision. This was determined to be the best balance between the fluctuations of year-to-year weather variation and the concept that, during their lifetimes, perennial plants mostly experience what is termed “weather” rather than “climate.”  A complex algorithm was used for this edition of the Plant Hardiness Zone Map to enable more accurate interpolation between weather reporting stations. This method accounts for factors such as elevation change and proximity to bodies of water, making mapping zones more accurate. Continue reading “New-And-Improved USDA Plant Hardiness Zone Map” →

Please Submit Trees Planted This Year

Wisconsin Tree Planting MapAutumn is a great time to plant trees. After the trees go in the ground, please take a few minutes to document the effort in the Wisconsin Tree Planting Map. The map was designed to help track trees planted to advance the state’s pledge to the Trillion Trees Initiative.

While the DNR may be able to track the ultimate destination of seedlings grown at the state nursery, or trees which have been funded by DNR grants, there are so many others planted across Wisconsin which go undocumented. The planting map was designed to help fill that void and to ensure that those trees are accounted for in our tallies.

Whether it was a planting of one tree or a thousand, take a couple minutes to submit your information through an easy-to-use survey.
