Introduction: In this lab you will apply what you have learned about succession to the ecological changes
that occur in an abandoned hay field. After only 5 years, several types of trees have begun to grow
where there was once only hay. You will observe, by counting, the number and types of trees that grow in
this field 5, 20, 50 and 100 years after abandonment.
Procedure A: For each figure 1-4, count how many of each species of tree are found in the field, using
the key as a guide. Add up all of the trees to find the total number of trees. You will then calculate the
percentage of each tree species at each observed time period. Use the following formula: Number of
specific free - TOTAL number of trees =
X 100 =
%
