Plant Species Found in the 2000/02 Forest Inventory Plots

in Prince Edward Islandby Glen F. Kelly

Introduction

The forests of Prince Edward Island contain a wealth of unique and special plants. This reportdocuments the diversity of forest plant species found during the 2000-02 Forest Inventory.

The 2000-02 Forest Inventory ground plots were based on a permanent location methodologythat builds on the National Forest Inventory grid system. Prince Edward Island has 804 plots withforest cover spaced out on a four kilometer grid and each plot is located and permanently markedusing Global Positioning System (G.P.S.) technology.

Each location has a number of subplots for large trees, small trees and shrubs, and groundvegetation tied to the grid location. The Large Tree Plot (LTP) for trees larger than 9 cm atbreast height (BH) had a radius of 11.28m and an area of 0.04 ha.. The Small Tree Plot (STP)for trees and shrubs of less than 9 cm in diameter at BH had a radius of 3.99 m and an area of0.005 ha. Four mini plots or tree regeneration and herbaceous plots were located on twoperpendicular lines 7.0 m. from the center location and each had a radius of 0.56m and an area of0.0001 ha.

Data Collection Procedures Herbaceous materials less than 1.3m in height were tallied by species and percent cover in themini plots. Regenerating tree seedlings 0.15 - 1.29m in height found within the mini plots weretallied. The LTP was also checked for other herbaceous species not found in the mini plots. Small trees and shrubs equal to and greater than 1.3 m. in height and less than 9 cm. in diameterbreast height (DBH) were tallied by species in the STP. Trees in the LTP were tallied by species. (Note: Other assessments were done in the plots but were not relevant to this report.)

Conservation StatusThe native plants catalogued in this report were ranked for their rarity using the Atlantic CanadaConservation Data Centre (ACDC) rating system. A species rarity, or Conservation Status “S”,rank is intended to reflect the level of concern for the continued existence of a species within theProvince. Non-native plant species are marked as “Eurasian” while mosses and liverwortsspecies were not rated and are marked as “Unranked”. A number of plants were only identifiedto the Genus or Family and these have not been ranked due to the absence of complete flowers orleaves needed to identify the species.

The following table gives the number of species in each category.

S2 Rare 19

S3 Uncommon 19

S4 Usually widespread 36

S5 Demonstrably widespread 180

The following lists are based on occurrence of the species in the ground plot but not on thefrequency within the plot. For example, Abies balsamea (balsam fir) was found in 586 of the 804plots but in these plots it could have been a large tree, a small tree and/or a regenerating seedling.
