[PCA] Fw: [Pollinator] Roads and pollinators - again

Thu Aug 31 14:26:57 CDT 2006

There is a NJ study from Rutgers that is on old field succession, which is analogous to roadside vegetation.  It shows that woody encroachment
happens over time as we all would guess.  However, from their conclusions specifically in New Jersey, mowing once every five years should accomplish what is needed in forested areas for the sake of safety.  Again, good luck to you. (Robichaud Collins and Anderson, 1994)

I think it is extremely important to recognize that mowing is necessary in many cases--but that the frequency could be substantially reduced (yearly, every other year, or every 3 years, etc., depending on the target area and the associated plant species, etc), and that the mowing schedule needs to be sensitive to the maturation of seeds, plant rarity, etc.

In some places, complete cessation of mowing would be disastrous to the populations-- but yearly or every other year would be more than sufficient.

In our area, preserves held by one well known nature conservation organization have lost a number of rare plant species due to *lack* of mowing. Previous to their acquiring of the property one preserve in particular was mowed once a year, late season. Unfortunately, the lack of mowing has caused a once fabulous botanical preserve to lose a number of fabulous species.

In this area, late October/early November works well for areas that need to be mowed.

In fire prone areas, like the pine barrens, another factor in necessity of mowing is the height of grasses & vehicles pulling off roadside, and the potential for fire. (Or so I have been told. Doesn't seem to me to be enough to warrant mowing several times a year!)

Mowing doesn't seem to me to be as simple as should we mow or shouldn't we--at least not here. 

It seems to be a combination understanding of the desired outcome, the necessity of management for that outcome, and the frequency and timing of the mowing if mowing is necessary, plus any number of variables that a habitat. 

Some plants need disturbance in order to thrive--Stylisma pickeringii var. pickeringii, being a local example. On the other hand, though, too much disturbance will destroy the population.

	I am regularly frustrated by the poor timing exercised by the folks in charge of mowing roadsides.  It seems when the blooming maxes, or the native grasses are peaking, or seeds are maturing, along come the mowers.

	This probably represents an opportunity for us conservation types to do good, by providing information and training about the best times and frequencies of mowing, and recognition of important native species.
