Annual decay rates in soil humus are monitored in 12 permanent forest plots within PEI National Park using year-to-year dry weight losses of standardized wood pieces (tongue depressors) as a proxy for soil decomposition. Climate change, pollution, dominant vegetation and land-use can all have profound influences on forest soil decomposition.

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.

The park measures forest regeneration and succession on 15 EMAN plots in deciduous and mixed forests on Beausoleil Island. The surveys report on the number, height class and survival of tree seedlings and saplings.

Radon is a radioactive gas that is found naturally throughout our environment. It is produced by the decay of uranium found in rocks and soil. Since radon is a gas, it can move freely through the soil enabling it to escape into the atmosphere or seep into buildings. Radon is invisible, odourless and tasteless, but can be easily measured with a radon detector.

Point Pelee National Park is the home to an isolated population of five-lined skink - the only lizard species found in eastern Canada. Monitoring involves overturning of logs and boards, and subsequent search for skinks. Dimensions of the cover object and its decay class are also recorded.

This dataset focuses on the status of forest stands and is used to monitor changes in this ecosystem, which makes up 95% of the Park. Considering the area’s history of logging, this monitoring is particularly important. The dominance of species, the internal structure of the stands and the rate of decomposition are the three field sub-measurements used to establish this measurement. For the first two sub-measurements, data from the 100 plots are collected in the summer over a 10-year cycle, 25 per year for 4 consecutive years.

This measure consists of 2 field measurements: Tree Crown Conditions and Stem Defects. These parameters are used to assess overall forest health in the park, as a reduction in crown cover can provide early warning signs of change in forest stand health and succession.

Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low micrograms per litre (ug/L) concentrations. In this study, the nest-defense behavior of adult male fathead minnows (Pimephales promelas) was observed in fish exposed for a full lifecycle to venlafaxine nominal concentrations. Nest-defense behaviors quantified were the time taken to contact a dummy intruder fish (on a flexible stick, held near each nest) and the number of contacts made during a 1 minute period. This study is the first to assess reproductive behaviors in fish exposed to an antidepressant over a full lifecycle.
