The cold stream is the purest stream water in southern Ontario and home to many
species of fish.
The bird diversity is highest in the Old Field Woodlot, followed by Majestic Pine woods
and the lowest in the Maple Ridge Woods.
The beauty and serenity of Majestic Pine Woods has intrinsic value to the people in this
Maple Ridge Woods is home to many birds and we have established many bird feeders
that are cared for by the local community neighbourhoods.
The Old Field Woods is home to many pesky skunks and racoons that get into our
composters and garbage boxes!
The basal area is low in the Old Field Woodlot, and it is dominated by a diverse shrub
The basal area is high in both the Majestic Pine woods and the Maple Ridge Woods,
which have dominant tree physiognomies.
We aged the woodlots using increment bores and counted the tree rings: Old Field
Woodlot is 20 years old, Majestic Pine woods is only 80 years old (rich soils make big
happy trees) and the Maple Ridge Woods is 250 years old.
Alpha diversity is highest in the Old Field Woodlot, followed by the Majestic Pine woods
and least in the Maple Ridge Woods.
Beta diversity is low between Majestic Pine woods and Maple Ridge Woods.
Beta diversity is high when comparing the Old Field Woodlot to either Majestic Pine
woods or Maple Ridge Woods.
Key Concepts and Terms
Population Growth: The change in the number of individuals during some period of time.
The calculation of population size is expressed as Pt2 = Pt1 + (B) – (D) + (I) – (E),
where Pt2 is the final population at the final time, Pt1 is the original or starting
population size, B is the number of births, D is the number of deaths, I is the number of
immigrants, and E is the number of emigrants.
