Table 1. Modified Daubenmire method for evaluating vegetation percentage cover.

Cover class	Percentage cover (%)
0	0
1	0–5
2	5–10
3	10–25
4	25–33
5	33–50
6	50–66

9	90–95
10	95–100

The cover class codes are shown with their corresponding percentage cover ranges.

Figure 3. Results of the InVEST modelling for the potential abundance of honey bees in Cumberland and Colchester counties of Nova Scotia. The model uses an LULC raster (a), a table of land -cover attributes (one iteration was informed by the literature and one was informed by field work) and a table of pollinator species as inputs to derive maps of nesting suitability (b) and floral resources (c). Combining (b) and (c) using Equation (1) generates an index of potential pollinator abundance on the landscape (d). Two iterations of the model were run, one informed by proxies and approximate values from the literature (i) and the other by field work (ii).
