Newfoundland & Labrador Wetland Restoration Inventory

The Stewardship Association of Municipalities is building an inventory of wetland restoration and enhancement opportunities in Newfoundland and Labrador. Healthy wetlands purify drinking water, prevent erosion, control flooding, increase biodiversity, and provide opportunities for fishing, hunting, and outdoor recreation. Wetland restoration and enhancement improves one or more of these benefits. 

A systematic inventory will focus the restoration and enhancement efforts of SAM and our partners, and will maximize benefits for Newfoundlanders and Labradorians.  

We need your help to build this inventory. If you know of existing wetlands in your local area which have been degraded or filled in and would benefit from restoration or enhancement, please contact Aaron Dale, SAM Conservation Coordinator, at 709.897.4676 or samconservation@gmail.com.

Know your Wetlands Classes, Part 2: Beautiful Bogs

Did you know that there are 5 classes of wetland in Canada? Learn to recognize them and get acquainted with the wetlands near you. You can learn about all 5 classes of wetland in greater detail by reading the Canadian Wetland Classification System. This post is Part 2 of a 5 Part series entitled Know Your Wetland Classes. 

The theme this week is Bogs, and if you missed Part 1 (Fentastic Fens), you can find it here.

Bogs

Bogs and fens are peatlands, meaning they have at least 30 cm of organic soil (peat). Unlike fens, a bog is ombrotrophic, meaning that the only source of water is precipitation, whereas a fen is minerotrophic, meaning it also receives water from surface and/or groundwater. Because of this, bogs are more acidic, nutrient poor and generally more dry than fens and other types of wetland. This creates a tough environment for plants, but those that do thrive here have developed some very interesting adaptations.

Pitcher Plants

Most interesting among these species might be the carnivorous plants that have adapted to a lack of nutrients by feeding off of insects. In Newfoundland and Labrador, we might be most familiar with the pitcher plant (Sarracenia purpurea), because it is the provincial flower. These vase-shaped plants entice insects to their water-filled leaf pouches with attractive patterns and colours. Once inside, smooth, downward-facing hairs inside of the leaves make it almost impossible for the insect to escape.  The insects drown in the 'bellies', where they eventually decompose and the plant can absorb their nutrients. 

Bogs in Newfoundland and Labrador

Bogs are the most frequent wetland type in Newfoundland and Labrador, and a common site as you drive across the province. A recent project to map the wetlands of the province using remote sensing will provide valuable insight into the total cover of the different wetland classes. Many of our stewardship communities have management units that include bogs, including Gambo, Gander, Winterland and Happy Valley - Goose Bay.

Know Your Wetland Classes, Part 1: "Fentastic" Fens

A few weeks ago I helped out my colleagues over at Ducks Unlimited Canada with wetland classification surveys near Deer Lake (a wetland stewardship community!). The field work was part of a large project to map the wetlands of Newfoundland and Labrador using remote sensing techniques. It was challenging, and fun, to classify over 30 wetlands in a three day period!

This week, I'll start with Fens.

Peatlands

Wetlands with a build-up of organic soil, or peat, are called peatlands. They are found in cool, wet environments where decomposition is slow, allowing for this build-up of organic material. Most of the natural wetlands in Newfoundland and Labrador are peatland, so chances are, you've seen one before! There are two types of peatland: Fen and Bog. 

Fens

Fens are peatlands that receive at least some of their water input from groundwater inflow. Water table fluctuates throughout the year, and is usually close to or above the ground surface. 

Fen Plants
Because groundwater is rich in dissolved nutrients and is less acidic than precipitation, fens have a higher diversity of plant life than their peatland compatriots, bogs. You'll find all sorts of neat plants here, including sedges, moss, Scheuchzeria (left) and Grass of Parnassus (right).
