Park staff visually evaluate tree health within 20m x 20m forest plots in August each year. Plots are rotated every 5 years (6 plots/year) and monitored according to term Ecological Monitoring and Assessment Network (EMAN) Protocols and Standards. Crown condition, diameter at breast height, and stem defects are used as indicators of tree health to help identify the symptoms of tree and forest decline.

Measuring decay rate in GBINP allows tracking changes in soil condition and processes. Decay rate was measured by placing wooden sticks in different forest plots and comparing dry wieghts of the sticks before and after the placement, in approximately one year.

The park is developing a protocol to monitor Northern Map Turtles as they congregate to bask along rock outcrops and shorelines on Georgian Bay. The measure will be completed annually through field observations of suitable basking sites. Turtles are long-living slowly-reproducing reptiles and play an important role of scavengers and predators in freshwater ecosystems. By monitoring the park will be able to track changes over time, identify potential threats and thereby achieving conservation goals.

Presence of exotic species often represents a level of disturbance in an ecosystem.The park samples invasive wetland plants along coastal transects, which include submerged areas. The focus of this measure are Eurasian watermilfoil and European phragmites. Currently the park has sufficient data only on the watermilfoil.

This measure tracks changes of the lake water level in the coastal ecosystem of GBINP. This is significant in driving ecological processes as well as acting as a stressor in the the park’s costal wetland ecosystem - as it is hydrologically connected to the lake water body, both at the surface and below.

GBI monitors water quality in coastal wetlands to report on nutrient loads resulting from human use of day-use areas. The park uses Water Quality Index to assess this measure - which is also a part of the Great Lakes Shoreline monitoring network.

Abundance and diversity of frogs and toads is a good indicator for assessing ecological integrity. The park visually counts adult frogs and toads in coastal wetlands after the breeding season. This method does not permit assessment of early breeding species and may overestimate frog abundance because these surveys coincide with mass emergence of newly developed frogs, which are subjected to very high mortality rates.
