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

On March 14, 2010 The Eastern Native Tree Society and Western Native Tree Society switched from discussion lists on Google Groups to a new discussion list in a Bulletin Board format at:  Posts made since the inception of the BBS on march 14, 2010 will be sorted and archived on the BBS. Click on the link above to go to the equivalent section on the new BBS. This website will continue to serve as a front end for the ENTS and WNTS groups. It will continue to serve as a repository of older posts, and will serve as the host site for special projects and features that are not well suited for a BBS format. Please visit the BBs for the latest information and trip reports.

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).

Liriodendron Budding

  • Liriodendron phenology/Project Budburst Gary, I went to Gautier, Ms., this moring to visit my parents. On the way back to Gulfport I stopped in nearby Ocean Springs, to check for budding on some Tulips I know of. Two of the four had bud swell and the other two had leaf out. These trees are growing near a small bayou just adjacent to a marshy area. I reported on them last year when flowering. These four trees are between 75-100 years old, I'm basing that on some tulips I had on property that went down in Hurricane Georges in 1998 that I had lumber cut out of. The four trees have heights to around 75' and CBH 10-12', these trees flood every hurricane and had around 4-6' saltwater during Hurricane Katrina in 05 with little effect.... more   Mar 10, 2010.
  • Phenology ENTS, Please post your observations of tree and flower budburst under this topic. Getting cabin fever in MA, today is the first spring-like day. I would especially appreciate LIRIODENDRON info. Thank you! Gary Beluzo Western Massachusetts Sent from Gary Beluzo's iPhone from Western Massachusetts... more March 4, 2010.
