Link to the Specification

This links to Ecosystems and
processes in the specification in section 3.1.6.6. – local ecosystems. This
links specifically to the main characteristics of a distinctive local ecosystem
and the ecological responses to climate. My project looks at the
interrelationship between vegetation and micro-climate in different locations
in a deciduous woodland ecosystem in a woodland in Woolland. I look at the
different characteristics that are influenced by the location such as the
vegetation and micro-climate

Aims of the Study

For my
study, I wanted to investigate a woodland close to my home in Woolland, to
research if there were any variations in the micro-climate in different locations
and the effect vegetation had on them. I hoped to achieve investigating micro-climate
features at four different sites during different weather conditions and
compare the factors that I had measured that make up a micro-climate. I decided
to look at differences between the five characteristics of a micro-climate, the
differences between these characteristics and where they were measured and the
extent to which these are closely linked. I want to investigate the
interrelationship between the location, vegetation and characteristics of
micro-climate and see how they affect each other.

General concept of the interrelationship between micro- climate,
vegetation and soil

There is a strong interrelationship between micro-climate,
vegetation and soil. The soil type affects the infiltration rates, this then
affects the moisture in the air and the growth of the vegetation. The
vegetation levels and type effects wind speed and light infiltration. The
canopy affects the levels of precipitation reaching the ground which in turn
effects the infiltration rates. The vegetation also has an impact on the
localised temperatures. These effects also happen on a small local scale and
have very strong interrelationships between the micro-climate soil and
vegetation.

Literature Review

A micro-climate
is the climate in a very small or restricted area, differing from the climates
of surrounding areas, there are usually four or five variables that together
make up the individual microclimate. Sunlight, Wind, Precipitation, Temperature
and Humidity. A ‘Forest Microclimate’ is “the wide variety of small-scale
conditions that can be experienced within a forest” (1).

 Geiger, Aron and Todhunter (2009) explored
that plant vegetation, especially canopy and tree stems shield the areas close
to the ground from solar radiation and reduce the mixing of air, so a below
canopy, more densely packed microclimate would differ greatly from larger, open
areas.

Location

The area I
am going to be investigating is a woodland in Woolland, Dorset. Located in the
Blackmore vale at DT11 0EW there’s a small woodland on the side of Bulbarrow
hill. Bulbarrow hill is the third highest hill in Dorset reaching 274m. The
area of the woodland I’m investigating is at the bottom of the hill and one of
the tributaries to the River Divelish’s source is found within the woodland. I
chose this location as it was convenient to get to as I was collecting three
times a day, over a three-day period when the weather was right for the
investigation. The woodland was close to my house making it easy to access over
the three days and I knew it had different levels of vegetation throughout the
woodland so it would work well in my investigation.
