This Spring Improve Survival Of Trees You Plant

Leave a comment

Every year the landowners of Ontario’s watershed areas collectively plant tens of thousands of trees. These trees help to restore the natural environment by protecting water quality in streams and rivers, providing wildlife corridors and purifying the air we breathe.

Unpredictable weather patterns mean it is even more important to keep planting trees. A number of crucial steps before and after planting will improve survival.

Right tree, right place

Factors such as soil texture, drainage and surrounding vegetation determine which tree species will thrive or die. Fine clay soils can hold trees like white cedar and Norway spruce. On the other hand, loose sandy soils are well suited to white pine and sugar maple. Silver maple and tamarack like wet sites, while larch and red oak will thrive in drier locations.

Road salt can contaminate the soil, but trees such as white spruce, larch and poplar have a higher tolerance for salt and these species are best for roadsides.

Preparing the land before planting will provide the best growth conditions for your trees. Clear areas of brush and invasive plants, such as European buckthorn. On larger sites, this can be done with a brush saw or a tractor and rotary mower to remove obstacles and provide growing space. Installing plastic mulch before tree planting is a great way to reduce weed competition and hold moisture in the soil. If planting into bare soil, seeding a cover crop of Dutch white clover is a great way to prevent excessive weed growth.

For the first years, control vegetation around the trees to make sure they have room to grow. This will give the trees the best chance of survival.

Get trees into the soil quickly

The roots of bare-root stock (without soil around the roots) will dry out very fast when exposed to sun and wind and need to be planted very quickly. Keep these trees in their planting bag until they are directly planted into the ground. Potted trees can be kept in a shaded area and watered until they are planted.

Mulch madness

Mulching is one of the best ways to keep your trees growing well. Organic matter applied to the base of the tree acts as a blanket to hold moisture, protect against extreme soil temperatures and reduce grass competition. Make sure to place mulch in a donut shape around the tree, so that absolutely no mulch is touching the base of the tree. This can cause decay of vital root-collar tissue. A two to four inch layer of mulch at an inch or two away from the trunk is enough.

Water, water, water

For the first few years of growth, a tree expends a lot of energy trying to establish roots in the soil. Watering can be very important  during this time if rainfall is sparse. Water the tree right after planting and weekly during hot, dry weather. But be careful not to over water, because soggy soil inhibits the tree roots from accessing oxygen. There are many circumstances when watering is difficult due to distance from a water source or the number of trees planted. For the Silo, Lisa Stocco.

When Are We Going to Get Serious About Invasive Species- Phragmites?

7 Comments

The Phragmites invasion was identified as the number one concern facing the Long Point area at this summer’s Long Point Biosphere symposium on ecosystem stresses.

In the pond adjacent to my house, a few Phragmites plants appeared about 20 years ago. Those few stalks then turned into a patch covering 15 per cent of the pond. It took 20 years but I’ve now eliminated it – although it has cropped up elsewhere on our farm. I realize what I’ve seen for an increase is small in comparison to what has occurred in some areas, for example, Phragmites dominates the ditches along Highway 402.

More than 10 years ago, Dr. Scott Petrie and Long Point Waterfowl were one of the first to research the expansion of Phragmites in the Long Point area. At that time, the potential threat was just beginning to be realized. Its threat wasn’t widely known outside Long Point except amongst waterfowlers and naturalists.

The last session of the legislature debated Phragmites as a part of the Invasive Species Act. This bill has currently had its second reading.

My concern as a landowner is to have the tools to deal with Phragmites. The Invasive Species Act doesn’t provide this kind of help. Ideally, the Act should contain an education plan, funding and ways to prevent spread. The Act puts an emphasis on landowners to control invasive species, but doesn’t provide the wherewithal to make it happen.

This is not to say the Invasive Species Act is all bad legislation, it’s just big on stick and small on carrot.

Now in talking about tools, we realize the challenges of controlling Phragmites. It spreads through both seeds and rhizomes and is just about impossible to control without herbicide.

I recently attended a St. Williams meeting on Phragmites, hosted by the Ontario Phragmites Working Group and Long Point Ratepayers’ Association, that focused on methods of control. Control alternatives varied from manual extraction, to discing it under, to experimentation with herbicides, to prescribed burns. Herbicides are the best alternative for large areas, but the issue is approval needs to be granted for application over water.

When Phragmites colonizes an area, it spreads quickly and prevents the new growth of other plants. It’s also poor habitat for wildlife. It impacts humans as well through loss of recreational opportunities, negative tourism impacts, decline in property values and blocked sightlines.

Purple LoosestrifeWhen Purple Loosestrife was the hot invasive plant, I was Parliamentary Assistant to the Minister of Natural Resources. In conjunction with the Ontario Federation of Anglers and Hunters, hit squads went into areas where Loosestrife was rampant and manually removed it. It’s not that simple with Phragmites, and we have yet to see this kind of commitment from government.

During the St. Williams symposium, we learned the City of Thomas has tackled Phragmites with minimal expenditure. The goal is to have the city Phragmites-free by 2020. Lambton Shores has also been aggressive and the plant is now 99 per cent under control in the municipality.

When Purple Loosestrife was first identified as an issue, it was thought to be the worst invasive plant in the province’s history – Phragmites now has that dubious honour. It will take a concerted effort by government, communities and individuals to take it on. It’s time to get serious! For the Silo, MPP Toby Barrett

Watershed Forests Returning On Former Farmer Fields

1 Comment
The Grand River watershed was 85 per cent forest 200 years ago. However, tree cover dropped to just five per cent by 1900 as land was cleared for farming and urban areas. Today, the tree cover has rebounded to about 19 per cent. Environment Canada suggests a healthy watershed needs a tree cover of about 30 per cent.
The Grand River watershed was 85 per cent forest 200 years ago. However, tree cover dropped to just five per cent by 1900 as land was cleared for farming and urban areas. Today, the tree cover has rebounded to about 19 per cent. Environment Canada suggests a healthy watershed needs a tree cover of about 30 per cent.

New forests are rising on old farm fields in Mapleton Township  in an effort to improve water quality in streams feeding Conestogo Lake reservoir.  About 70,000 trees are being planted this year and next on two parcels of land totalling 40 hectares (100 acres) on the north side of the reservoir.

The GRCA is planting a variety of species that are native to the area, including spruce, tamarack, white pine, bur oak, silver maple and cottonwood. In addition to the new forests, the GRCA will also do some reshaping of the landscape to create some seasonal wetlands that will also help improve water quality and provide additional habitat.

As the trees grow in coming years, the areas will quickly become home to a variety of animals, such as deer and wild turkeys. Later, as the forests mature, it’s expected that several bird species including scarlet tanagers, ovenbirds and great horned owls will take up residence. A 12 hectare parcel near Wellington Road 10 and Concession Road Five has been planted this year. The second parcel of 28 hectares is near Concession Road 5 and Sideroad 15. About 18 hectares has been planted this year and the rest will be planted in 2015. The land was acquired by the GRCA when it built the reservoir in the 1950s. It has been leased to farmers since then.

These two parcels of land were prone to erosion which sent a lot of sediment down the streams into the reservoir, explained Ron Wu-Winter, watershed forester with the GRCA. In addition, the sediment also carried nutrients – phosphorous and nitrates – which are found in manure and commercial fertilizers. The nutrients would spur algae and plant growth in the reservoir, resulting in lower water quality.

The northwestern part of the Grand River watershed contains some of the best farmland in Ontario. As a result, the forest cover is some of the lowest in the watershed. Forest cover is estimated at 15 per cent or less. A healthy watershed should have forest cover of about 30 per cent. Trees help raise water quality in several ways. They soak up nutrients in the soil, so reduce the volume that runs off the surface into a watercourse. Trees along a stream shade it, keeping it cooler in summer which is good for some coldwater fish species.

The total cost of the project is about $150,000. About $50,000 was contributed by the Grand River Conservation Foundation. It is also supported by the Trees Ontario Foundation which is contributing $65,000. For the Silo, Dave Schultz.
