Oh it is a beautiful day! A nice day for a walk in the woods. We can meet at the hay field down the road and walk in, be careful to park on the field side of the road because as you will notice the field across the way it hasn’t been hayed or mowed for years and show signs of early succession with perennials, shrubs and tree seedlings and at the stone wall on the edge of the road the rosa multiflora and autumn olive has taken over and you don’t want to get too close. It’s about 1/4 mile hike thru the fields, but it shouldn’t be too bad as the fields have had its’ first cut and is just starting to grow anew. As we look what is growing here we see timothy, clover, vetch and annual and perennial grasses such as orchard, rye, switch grasses and maybe other plants that we might consider to be weeds. but for the person who is cutting this field they do try to keep out plants that might be poisonous to horses, cattle and other livestock and introduce plants that might have higher nutritional value. We notice an area that hasn’t been cut and the reason for that is that there are ground nesting birds like bobolinks or meadowlarks who’s brood has yet to fly off from the nest. How this field is maintain is a factor in what plants grow here. If the field were to be mowed once a season we might find that plant species would change over time, for plants that might take longer to flower and set seed might start to replace those that can survive being cut two or three times a season, and if as some time happens, this field is used for grazing of livestock, again over time the plant composition might change again due to the greater input of fertilizer in the form of manure and what plants can survive being grazed on.
We move on and before we reach the edge of the woods we come upon brook and some wetlands and we notice the signs of a past beaver encampment on the brook, large girdled dead trees some distance from the brook, beaver chewed stumps and maybe the remnants of their dam. When the beavers were here they would have ponded the area upstream, the expanded the wetlands that were already here and change the flow of the brook downstream. The area around the pond would have changed ; trees were taken down by the beavers or died from the soil becoming saturated or being girdled and some remain standing. Whether the beavers were evicted or they had moved on to new food sources, this is area is one of transition with the pond being gone, the wetlands area being reduced as the soils dry out and others plant species able to grow here again. Even if the beavers hadn’t populated this area, this brook and surrounding wetlands might still be going to changes; from changes in the brooks’ flow either from changes in precipitation or divergence of the water flow upstream, whether natural or man-made and/or deposition of sediments in the area from land disturbances upstream.
As we walk along the edge of the wetlands to the beginning of the wooded area notice that forests’ edge is dense with many shrubs and younger trees we might also notice that some non-native and some invasive plants have managed to get a foothold here with their seed being deposited or blown in from surrounding areas. We walk in to the woods we notice it is a bit cooler, the sunlight only reaches the ground in little patches, the understory plants and trees seedlings are more scattered. As we walk on we see the changes in tree dominance in one area beeches might have larger numbers than oaks or maples. There are larger size beeches with surrounding younger ones that haves spouted from the older trees roots. we travel a little farther on we see oaks and maples mixed with white pine, white ash, hemlock and spruce. Off to side there is dense hemlock stand with nothing growing underneath except for some smaller hemlocks that may be older than their size would indicate, their growth is slow as they wait for an opening when the sun might reach them and then they can take up the space allowed them. We also notice changes in the understory plant material some plants in abundance in one area but not in other areas, including ground covers, sometimes more plants growing where more sunlight reaches the ground. Maybe a tree or trees were blown over in a wind storm allowing more light to reach the ground. We see evidence of past openings with ‘pillows and cradles’ which are mounds next to depressions which indicate that trees had been blown over raising the roots out of the ground and being that the trunks or roots having decayed and the soil dropped where the roots were.
As we have been walking we have notice series of stone walls which indicated that this land had been cleared of forest and was either farmland or pasture maybe dating back more than a couple of hundred years ago. At some point this area was abandoned as farmland and allow to regenerate to forest, we can assume this from the few trees that may have been here for a hundred years or more. Yet we notice that many of the trees by their size may not be more the fifty years old, so we can also surmise that these woods had been logged again and the older trees were left because they didn’t have any timber value or were in locations too difficult to cut and remove.
We all have different perspectives to what these different habitats are and what they mean, and we are just beginning to understand how each of these habitats do effect each other. How changes in one area might have impacts on surrounding habitats from natural or man-made changes or how continuous changes in each affecting the other. They are unique environments that are woven together by the soils, types of organic debris, micro-organisms, moisture and water, flora and fauna. One can spend a life time observing and studying it and still not know or understand it all.
We have reach the top of the hill from here the trail to the right heads off to a old gravel pit long unused and you would see that plants are just starting to get a root hold, just here and there and most likely will take decades if not a century to built up enough organic material to once again become a forest. To our left we look out to see the development below, residential neighborhoods, shopping areas. One thing that might strike you is the vast difference between what we have just experience with our walk and much of our man-made landscapes which mainly is one of well structured islands in seas of black and green. Trees and plants nicely spaced, evenly organized, one of these, three of those or massed plantings for that visual impact. The reason for our walk is about landscape zoning ordinances for if we didn’t have any ,how much worse might our landscapes look? Areas of lawns might be just black top or left as gravel. It would be left up to those who enjoy landscapes and gardeners who always want to add something new to their homes verses others who just don’t care what it might look like. Some we create laws about landscapes and lawn in the hope to improve the quality of all our lives, to bring our changes to the natural environment from development and keep the natural integrity of the supporting landscape. The trouble is when laws are written they meant to be clear and understood by the majority and carried out by good hardworking folks who don’t know much about the nature of trees, plants, soil habitats, what their requirements and how they might impact the natural ecosystems. We can try to control issues of water, pollution, vegetation and it impacts on us and our environment, we write ordinances that call for a tree every 35 feet, shrubs every 6 feet along the perimeter which is certainly better than none, but how does that fit to a natural environment? When ordinances requires ‘ x’ number of trees and shrubs for ‘x’ number of parking spaces planted within the lot; where rarely they remain healthy or even survive given root space, soil conditions; might it not be better to use that plant material to create natural buffers and leave the parking lot for cars.
We have over time develop an ideal of what a good landscape should be, that includes lawns, foundation plantings and with islands here and there. Yet next to the natural landscape does it really fit or does it belong? What if I decided to stop mowing my lawn, allow it to become a meadow; might someone come to my door and cite me for an un-kept lawn? How would I explain my reasoning to that person who can understand what a lawn should be, but not a meadow? How would the neighbors feel if I let my landscape go ‘la natural’, let nature take its course? As more and more of the natural landscape is being taken over by ‘us’ and we replace what was there with what we consider good landscaping, with the technology and equipment to change our environment on an unprecedented scale and no way of knowing the long term effects we might be having on whole ecosystems . For our parts as landscapers, designers it is time to reconsider what is a good landscape, one that takes the whole environment in account, addresses our understanding soils, our choice of plant materials (native and alien), including grass species and give them greater importance in our changes of the natural landscape.
