Pine forest is a place where the environment is sacred and we must protect it, says a new study by researchers at McMaster University.
The study, which will be published in the journal Forest Ecology and Management, highlights the importance of protecting the forests ecosystem and what to do if your property is threatened by invasive species.
The research team conducted a tree census to understand how forests in the region were affected by invasive plants.
The paper shows that many species have been found in the forest canopy, including several species of pine and whitebark.
A tree census is a very good way to understand whether or not trees are there or not, says lead author Marie-Claude Gagnon, a research associate in the department of forestry and conservation.
The tree census was conducted over a six-month period between June 2016 and May 2017.
It included surveys in the forests of eastern Ontario, southern Alberta and Manitoba.
The team also collected information on the species of invasive plants that were present in the trees, which are known to be invasive species, and their effect on tree health.
In a typical survey, researchers will collect data from trees that are close to a survey site, which is when they are in contact with the trees and they have an understanding of where they are and where they come from.
The data collected includes detailed information on where the trees were collected and where the plant species that were collected were located.
The scientists then compared the results with information about the tree species found in each of the six different surveys.
The results showed that invasive plants were the main cause of the decline in tree cover and tree health in the six studies.
Gagnons research team also found that the number of invasive species was increasing in the last decade, with the number growing from 7.7 to 21.3 per cent of the total trees.
“We’re finding that we’re seeing the species in the tree canopy is increasing, and that’s the main issue,” Gagn, said in a news release.
“This means that the ecosystem is becoming more susceptible to invasive species.”
The research paper states that it was not clear how the tree census data was obtained or how the invasive species were identified.
“These studies are important because we don’t know if the invasive plants are present, where they came from and how they’re affecting the ecosystem,” Gagne says.
Gagne notes that the survey data also showed that there were differences in tree growth between the northern and southern Ontario forests.
This is not the first study to look at invasive species in trees.
A previous study by Gagn and colleagues found that invasive species such as whitebarks and white oak have increased in the pine forests in Ontario since the early 2000s.
Researchers also noted that many invasive species are in trees in other regions of the province.
The authors suggest that this new research shows that forest management can be improved by keeping a close eye on the growth of native species and looking for indicators of the species’ impact on the forest.
The new research also shows that the decline of native forests has been linked to the introduction of invasive plant species into the region.
“When you look at these data and you see that they’re declining and we don, the issue is how do you control that?
Are we doing enough to control it?” says Gagn.
The report found that a number of areas of Ontario were experiencing higher rates of tree mortality compared to areas with higher tree canopy cover.
For example, in eastern Ontario there were more whitebars in the northern forests than in the southern forests, and whiteoak in the western forests had the highest mortality rates.
The researchers say that the study will provide a new tool to measure the effects of invasive vegetation on native trees in the future.
“It’s really important to understand what is going on in the ecosystems of the forest, especially in areas where we’re not having these invasive species,” Gagner said.
The work was supported by the Natural Resources Conservation Council of Canada.
