Mt Pleasant Farm – March 2016

There are signs of spring at the Howard County Conservancy’s Mt. Pleasant Farm but the trees still look very bare. Earlier in the month I posted about the Wood Frogs in the Honors Garden pool. Last week, the frogs (and their loud clacking) were gone, but the tadpoles were beginning to hatch. They were easiest to see on the rocks. They are algae eaters and the little pool has plenty for them to eat. Notice that there is also a tiny snail just above the water line.

The moss growing on the parts of the rocks above the water looks very green right now. Soon there will be a lot more tadpoles in the water below since there is a large egg mass that has not hatched near this rock.

I took advantages of the absence of leaves to capture a stump that is usually hidden by brush. It has shelf fungus

And wood pecker holes

And lots of moss growing on it.

It is near the spot where skunk cabbage grows (previous post is here).

The streams are gurgling (and the paths are usually muddy) this time of year.

The farmhouse is visible from the meadow with the deciduous trees still bare.

I stood photographing a mockingbird for several minutes. At first I thought the breeze was ruffling the neck feathers but then I realized that the neck moves a lot as the bird creates his sounds (mockingbirds have quite a repertoire).

Squirrels are still finding last season’s nuts – and eating them noisily. I would not have noticed this squirrel without that noisy munching.

The maple ‘tree within a tree’ is still one of my favorite stops along the stone wall. Theorizing about why it is that way….and looking for snake skin sheds which seem to be there frequently…are always a hit with hiking groups.

These shelf fungi caught my eye – like little steps up the large branch.

Last season’s dogbane still holds some of its seeds in the meadow.

So even at the end of winter – beginning of spring, there is a lot to see here. It is a calm before the riot of growth that comes in April and May.

Wood Frogs

The Wood Frogs were active yesterday in the little pool in the Honors Garden at Mt. Pleasant Farm. It was a warmer day than we’ve experienced anytime recently – getting into the 70s. Some of the frogs were warming in the sun on the rocks beside the pool

Or lounging on the surface of the water.

There are so many of them that they tend to float into each other and then there is a flurry of activity as they loll on the surface.

There are already some eggs in the pool. It’s only the beginning. And then the pool will be teeming with tadpoles eating everything in sight.

Eventually the tadpoles will become frogs and the pool will be cleaned out and the pump turned on – the pool becomes the welcoming fountain of the Honors Garden in the summer.

Natural History of a Place

I went to Belmont Manor and Historic Park in Elkridge, MD frequently enough over the past year to observe it in every season. Last summer a large English Elm on the front lawn of the Manor had to be cut down (Dutch Elm Disease). I took this picture shortly before it was cut down - the picture taken from an angle that the dead part of the tree didn’t show too much. A month later the tree was gone, the stump and exposed roots dug out, and new sod put over the wound. A month later and it was hard to tell where the tree had ever been. The episode stirred some thoughts about the natural history of a place and the significance of our actions on that.

The English Elm was planted – a non-native to North America. Whoever made the decision to plant an English Elm may have been wise in the end because this one lasted longer than most of the American Elms against Dutch Elm Disease.

The pond further down the hill was probably dug in the 1980s. It was probably always a wet area. There was probably a vernal pool there in spring. Lots of wood frogs would have successfully laid their eggs there and new frogs would have emerged. Now the pond has fish – that eat frog eggs.

In the 1900s – the area in front of the house was open. For some of those years it was pasture for horses. The forest would have been different. At the beginning of the century there might have been American Chestnuts in the forest. They would have been noticeable for their size and their nuts would have been gathered every fall – by people and squirrels (and other animals too). There is no tree that has quite filled the niche of the American Chestnut that was wiped out by the mid-1900s by the Chestnut Blight.

Earlier in the 1800s, many of the trees would have been cut for fuel. There were a lot of ironworks. There were massive erosion events when the forests were cut and the Patapsco River – downhill to the north of Belmont – received a lot of sediment changing it from a navigable river to a shallow, easily flooding river by the early part of the 1800s.

Prior to anything being built on the hilltop where the Manor House is today – the area was forested. The chestnuts were the big tree and the Europeans were impressed by the richness of the life in the rivers.

There is so much that we did not preserve…and that we still don’t quite know how to sustain.
