What is PlantWatch? • PlantWatch is part of the NatureWatch series. • It is a volunteer monitoring program to help identify ecological changes that may be affecting our environment.
What is PlantWatch? • PlantWatch is a joint initiative between Nature Canada and Environment Canada’s Ecological Monitoring and Assessment Network (EMAN). • PlantWatch partners include representatives from each province and territory.
What is PlantWatch? • PlantWatch is a national phenology study. • Phenology is the study of important events in the lives of plants and animals. • For PlantWatch this is when a plant flowers as the weather warms in the spring.
What is PlantWatch? • The goal of PlantWatch is to encourage Canadians to help scientists find out how our natural environment is changing due to changes in climate. • We can get involved with this project by recording flowering times for selected plant species and reporting data.
Why watch plants? • By watching plants you can learn about Canada’s botanical diversity and help scientists track the effects of global warming and climate change. • Plants are measuring sticks for climate change.
Climate Change • Globally the earth’s temperature has risen 1oC. • Predicted temperature increase of 3-4oC in the Atlantic Provinces. • Winter freeze-thaw events becoming more frequent. • Precipitation (including snowfall) is expected to increase.
Why watch plants? • The plants chosen for PlantWatch bloom in the spring as they accumulate heat (when the temperature rises). • Some of the species are flowering a month earlier than they were a century ago.
Why watch plants? • Reporting on PlantWatch species in your community can help researchers discover how the climate is changing. • Any contribution you can make is important.
How to get involved • Climate is changing and we need to monitor these changes. • We need more PlantWatchers in Newfoundland and Labrador! • Anyone can become a PlantWatch participant! • It’s an excellent activity for families, classrooms and outdoor groups.
How to PlantWatch • Choose your plants • Use the PlantWatch website (www.plantwatch.ca) or the PlantWatch guide to find out what plants are being watched in your area. • Be sure to select plants that you can observe everyday.
How to PlantWatch 2. Select your site • Choose plants growing in an easy to access, flat area. • Avoid sites with unusual temperature or light conditions.
How to PlantWatch 3. Mark your territory • Mark the plant (or patch of plants) with a tag.
How to PlantWatch 4. Watch your plants • Read the species’ descriptions on the PlantWatch website or in the guide to help you recognize “first bloom” and “mid bloom” and “leaf out”. • Record the dates for each.
How to PlantWatch 5. Submit your observations • Submit observations directly on the website. or • Mail the data sheet to the PlantWatch Coordinator for Newfoundland and Labrador.
Species selected for Newfoundland and Labrador
Blue-bead lily Crackerberry Trembling aspen Labrador tea Coltsfoot Dandelion
Larch Lilac Red Maple Strawberry Sweetgale Starflower Rhodora
Crackerberry General: • It is a low, erect woodland plant (10 cm tall), that grows in colonies. Leaves and twigs: • Smooth edged, oval leaves with parallel veins. • Four to six leaves form a ring around the stem. Flowers and fruit: • Each plant has a single cluster with four showy bracts that look like petals. • In the center are tiny flowers that are green or purple or cream in color. • The fruit are red berries.
Crackerberry Habitat: • A forest plant, crackerberry tolerates a variety of soil conditions. • When the flowers are open, black central dots are visible (stigmas). • First Bloom: when the first flowers are open. • Mid bloom: when 50% of flowers are open in observed plants.
Dandelion General: • Common plant, 5-40 cm tall. Introduced from Europe. Leaves and twigs: • Deeply toothed leaves grow from the base of the plant. • Leaves appear before flowers. R. Hopkins
Dandelion Flowers and fruit: • Flower heads are yellow and the flower stem is hollow and leafless. • After full bloom, white, fluffy, round balls of seeds appear. The parachuted seeds are blown away by the wind. • Main flowering is in spring, but scattered blooms continue all summer. • Note: flowers close at night and on cloudy days. R. Hopkins
Dandelion Habitat: • Dandelions grow almost anywhere, but are common in wastelands and cultivated areas. Sampling: • Make sure your patch is not mowed until your bloom observations are made. • Choose plants at least 10 m away from buildings. • First Bloom: when first flowers are open. • Mid bloom: When the first seed-head opens, forming a white, fluffy ball of seeds. R. Hopkins
Labrador Tea • General: • Erect evergreen shrub, up to 1 m tall • Leaves and twigs: • Leathery, narrow, oblong leaves (2-5 cm • Long) with matted hairs on the underside. • The edges of the leaves roll under to • help retain moisture. • Twigs are densely covered with hairs.
Labrador Tea • Flowers and fruit: • Five-petalled, white flowers, occur in rounded clusters at the branch tips. • Habitat: • Shade-intolerant and often found on moist to wet soils. • Common on open peatland dominated by sphagnum moss and in open-canopy coniferous forests.
Labrador Tea Sampling: • Select a typical patch of plants, if the plants are very abundant, mark off a l-metre-square section to observe. • First bloom: when the first flowers are open in the observed plants (3 places). • Mid bloom: when 50% of the flowers are open in the observed plants.
Larch R. Hopkins
Larch General: • Medium-sized coniferous tree; grows up to 20 m tall, with scaly bark. • In the fall, the needles turn yellow and drop. Leaves and twigs: • The long, slender branches have small woody stumps that produce the needle bundles. • Needles, 1-2.5 cm long, emerge as soft green tufts during spring growth. Each tuft can have 10-20 needles. R. Hopkins
Larch Flowers and fruit: • Male and female cones can appear on the same branch. • Male cones: small mounds of yellow-brown pollen sacs that fall after shedding pollen • Female cones: pinkish-purple mini-cones about 1 cm long. • Note: Observe male cones only for PlantWatch.
Larch Habitat: • Grows in moist to wet areas. • First Bloom: when first pollen is being shed by the male cones (3 places). • Mid bloom: When 50% of the male cones are shedding pollen. • Leaf out: When the tufts of the needles are lengthening and starting to spread open at the tip ( 3 places).
Red Maple General: • Deciduous tree with grey bark. Flowers appear before leaves. Leaves and twigs: • Twigs are slender, shiny and dark red with whitish dots. • Leaf buds are rounded, dark red-wine in colour. • Leaves are red-tinged in the spring, green in summer and bright red in the fall.
Red Maple Flowers and fruit: • Flowers emerge from dark red buds in the spring. • Male and female flowers usually grow on different branches of the same tree. • Female flowers are red while male flowers are yellowish green. • Note: only observe male flowers for plant watch.
Red Maple Habitat: • Trees are usually found in swamps and moist soils. • Moderately shade tolerant and they also grow in dry areas. • First Bloom: when the first male flowers are open (3 places). • Mid bloom: when 50% of flowers are open. • Leafing: when the first leaves push out of the bud and unfold completely (3 places)
