Liriodendron Project

 

Liriodendron Project

We are exploring Massachusetts and New England for the northeastern extent of the Liriodendron tulipifera distribution. Significant progress is being made on finding (and extending) the published range of the species.  I am taking a sabbatical next academic year so I will be doing field work from about the middle of May to the following February, whenever the weather permits.  I hope to use GIS to map the distribution of several disjunct species (with CBH, height, and other attributes) in New England. - Gary Beluzo

 

A CALL to ALL ENTS: If you could send me First Budburst/Leaf out and First Flower for Liriodendron in your area acroos the eastern United States that would be most helpful for establishing a distribution-wide data set.  Data is open to all ENTS members. LATLONG is optional but greatly appreciated.

Budburst/First Leaf: Report the date at which the first leaves are completely unfolded from the bud.  For trees or large shrubs you will want to make sure there are at least three places on the tree or shrub where budburst has occurred.  The leaves need to be opened completely and the leaf stem or leaf base must be visible (you might need to bend the new leaf backwards in order to see those).  For conifers record when the new needles have expanded beyond the length of the bud scales.

First Flower: Report the date at which the first flowers are completely open. You must be able to see the stamens among the unfolded petals.  For herbs (non-woody plants), look for the date when the first flowers of one patch are blooming.  For trees or large shrubs you will want to make sure there are blooms on at least three places on the tree or shrub.  In case of Hazel, Alder or Pine trees (or other conifers), look for the date when they start releasing the powdery, yellow pollen from their cones or catkins (cone-like flower clusters).
