Community Walk with Ryan Trapani

On August 12, 2023, Ryan Trapani of the Catskill Forest Association led

a community walk through our parcel on Upper Sahler Mill Road in Olivebridge, NY. We started the walk in a field close to the road where Ryan noted that Olive and other towns in Ulster County do not have a lot of open land–so much of it is mature forests–and that open fields provide much-needed food for pollinators.

At the border of the field Ryan pointed out some of the “pioneer” trees

that grow in the early stages of a forest, such as Black Locusts and

Black Cherry and he noted that there is much more tree diversity near

roads because of the sunlight. He also spoke about the diversity of

our area in general. As both Sam Adams and Frank Parisio noted on

earlier walks, this area is a literal zone between the mountains to our

north and the plains to our south. Many species of both fauna and flora

here are at the farthest reaches of their ranges.

As we walked into the forest, we crossed a large expanse of hay

scented ferns. Ryan noted that while most people find them very

beautiful, they block tree growth because of their allelopathy. This

means that they discharge, through their roots, a form of herbicide that

inhibits the growth of competing plants. “Ferns are what the deer

leaves behind and that’s why there is so much of it.” He also surprised

us by saying that despite what most people think, we have fewer deer

now than a few decades ago–it just feels like we have more because

they feed closer to the road where there is better food. He noted that

the bear population seems at peak level.

In the forest we saw plenty of Hemlock–the most shade tolerant of

trees–as well as Black Birch, Red Maples and a few White Oaks, which

are so valuable ecologically for their acorns. He encouraged us–as he

does many landowners who engage the Catskill Forest Association to

help with forest management–to selectively cut down maples that are

competing with white oaks. As we went deeper we found some

Shagbark Hickories, Poplar, Butternut and also Red Oak–which is

surprising because it is not a very shade tolerant tree. The Butternut is

probably one of the last stragglers from when this land was part of the

large Merrihew farm (Butternut was one of the crops that they grew).

Ryan taught our group how to spot a healthy tree by looking at the

crown, or the part of the tree that has full, live branches. If less than

60% of the tree has full, live branches, then it is not considered healthy.

He also cautioned that many people mistakenly cut down the biggest

tree in a stand of trees, thinking it is the oldest when in fact it could just

be the fastest growing. Age can be estimated by the size of the flare of

the trunk where it meets the soil. A wide flare enables a tree to sustain

high winds better. Instead, it’s best to make sure you are cutting the

oldest tree in order to give the younger trees time to fully mature.

Lastly, he showed us a pit and mound, which forms when trees topple

over. He said you can tell what caused the tree to fall by the direction of

the mound–be it from a nor’easter or a hurricane from the south.

Everyone who joined the walk came away with more knowledge and appreciation for the diversity in our forests. We are grateful to Ryan, for an informative and inspiring morning!!
