Thank you sir, may I have another?

It has happened yet again - *sigh*. Wild potato vine (Ipomoea pandurata) has once again been cut to the ground.

Here's the problem, this plant, an herbaceous vine, (related to that chartreuse green windowbox favorite) existed in an area that was made into a recreational park. Despite all thoughts to the contrary, the plant came back a few years after it had been hacked to the ground to create said park. However, the plant doesn't know that things have changed. This (unnamed) park is now manicured and all things not trees get weed whacked. (This seems to be true of all NYC Parks - unskilled labor + pruning equipment = death to all plants not 50 ft tall. I'm not exaggerating). Imagine, a vine growing up a fence in a highly managed park. How unseemly! thwack

Why care? Well, wild potato vine is a New York State rare plant. And this site is its only occurrence in New York City. I am meeting with the park manager next week to discuss long term solutions to protect this plant. Which I've done every year around this time. My suggestion for 2007 is going to be a security guard.

LAs with Attitude

In reviewing the plant list for a certain project along the Bronx River, I finally embraced the fact that many landscape architects are very resistant to using natives.

For starters, I pointed out a number of invasives trees, shrubs and forbs that were on the list and suggested suitable native alternatives. I also commented on the compatibility of other exotic species with site conditions and proximity to natural areas.

This was one comment back...

Cotoneaster apiculatus and Spiraea japonica (both of which I said were invasive) are only found in the medians on East Tremont and Devoe. They were chosen for their hardiness in order to survive this hostile environment (because native plants are never found in hostile environments?!? she said dripping with sarcasm). If NYSDOT agrees we can replace the Cotoneaster with Arctostaphylos uva-uri or Myrica pensylvania, and the Spiraea with Itea virginica or Clethra alnifolia (my suggested replacements). You'd think I was asking them to donate a kidney. Sheesh.

The rarest in the land

Poor Torrey's mountainmint (Pycnanthemum torrei). There has been so much hooey over this population (then scroll 4/5 down) of the globally rare plant. It used to be part of the gorgeous! pristine (in some sections)! rare plant inhabited! 130 acres Kreischer Hill parcel, which was owned by the NYC EDC.

But conservation was not to be. Instead of thousands of years old glacial till sandy soils with their concomitant NYS rare communities and species, we have - what we've always needed! - Target, Home Depot, Bed/Bath/Beyond and a Christmas tree store. Hooray! That was certainly worth destroying the uncommonly occuring, sexually reproducing population of American chestnut. But that's just imho.

*Sigh*

Presently we are trying to conserve the population in situ (stop snickering!). This summer, we did a census of the mountainmint population. A transect was set up parallel to Veterans’ Road West. Every meter was marked off. Perpendicular to transect, 1m squared plots were set up. Within each plot the following data was collected – number of plants, number of individual stems, number of shoots, length of all stems, and the presence and number of flower heads. Casual observation suggests that the plants are grouped in clusters along this transect. This data will confirm whether or not this is the case. If so, further environmental factors will be examined to determine causal factors.

The Garden State

Good things going on in New Jersey:

A new watchdog organization forms to protect the Highlands
With increasing pressures to further develop and fragment the New Jersey Highlands, New Jersey Conservation Foundation and its conservation partners are forming a new watchdog organization—the New Jersey Highlands Coalition.

Statewide vision for land preservation
Garden State Greenways, is available free to conservation advocates, regional and local planners, government agencies, community leaders and others.

Plants 0, Recreation 1

This is a charming little change in Parks' policy from allowing only passive recreation to now installing mountainbike trails in natural areas throughout the city. These pictures are from Cunningham Parks in Queens. I have a couple of issues, aside from how devastating this will be to ferns and wildflowers of the forest floor.

The propaganda (which, please note, was written by the mountainbike person doing this work), speaks of erosion:

"There's a common misconception that bicycles cause erosion damage to the trails. In response, a group of local mountain bicyclists decided to band together and educate themselves on the science of trail erosion and how bicycles could be ridden with minimal impact. Fueled with information provided by the International Mountain Bicycling Association (IMBA) and the US Forest Service, a management plan began to take shape."

First, I would like to see the literature that supports the contention that mountainbikes don't erode trails. But that will never happen. You know why? It doesn't exist. You can, I imagine, minimize erosion, but there will always be erosion associated with mountainbiking.

Second, you want to see their answer to erosion? Look below...













That ditch off to the side? THAT is the result of their managment plan. These are placed every so often along the trails where there are slopes to encourage water (and thus water borne entities, such as soil) to pool. There is still plenty of erosion happening. What is no longer happening is the soils ending up on sidewalks and roadways when it rains. Now the soil settles into these little pools. So it keeps civic infrastructure tidy, but does nothing to retain the uppper soil layers. aka the seed nursery aka the bed of all future trees.


This is utterly awful. Acres and acres of destruction caused by all terrain vehicles - those off road motorized contraptions. Cops tell the drivers to go in the parks - these things are illegal on city streets. But see what happens when cops send these guys into the woods? This is a living graveyard. Once those trees die, nothing will take their place. Shameful. Why doesn't the Parks Department put in perimeter protection to keep these vehicles out? It's a cheap and easy solution, but there is obviously no will.

Scary Seton Falls Park

A little early for Halloween - scary but true story...

While monitoring vegetation in Seton Falls Park in the Bronx along Rattlesnake Creek approximately 100 yds from the falls area, I noticed 3 boys, about 13 years old, congregating nearby. When I asked if they needed some help, they responded with lewd and threatening comments, and then ran off. I was a little rattled, after all I was in a ravine, unseen (and probably unheard) from the street. About 10 minutes later, they returned to throw rocks at my head. Charming. At this point I ditched the field work and called the police as I promptly left the park. Once the two officers arrived, they drove around a bit to look for the kids, but no luck.

In the midst of the melee, I did come across new plant finds for the park: large-toothed aspen (Populus grandidentata) and the forb ditch stonecrop (Penthorum sedoides). Both are native, the latter is NYC-rare.

Orchids Found in SI

Today I went out with my pal Ray to root around along Staten Island's south shore...won't say exactly where...and we found two orchid species new to City records – large coralroot (Corallorhiza maculata) and bog twayblade (Liparis loeselii). Large coralroot lacks greenery - it has tawny brown stems and no leaves. This is because it does not photosynthesize. It is saprophytic, meaning it feeds off organic matter, like fungi. It is added in its nutrient intake by a short, stubby, branched root that resembles coral. Small white, purple spotted flowers appear in late summer.

As the name suggests, bog twayblade is found in wetland, open habitats. It has unremarkable yellowish-green flowers that are only 1/4” long that bloom in late summer.
