Battling {the lack of} Biodiversity:A Butterfly & Hummingbird Meadow Ashley So Carly Starke
Overview • Materials • Methods • Data Analysis • Implications • Taking Action • Conclusion • Statement of the Situation • Identification of the Problem • Proposed Solution • Background • Ethical Issues • Objectives • Rationale
Statement of the Situation • Lack of biodiversity in animal species • Unused space and empty land • Development and construction • Decreases amount of plants • Food source and habitat
Solution • Butterfly & Hummingbird Garden • Wildflowers
Background • Local species to central NJ • Hummingbirds • Arrive mid-April and stay until early September • Ruby-throated and Rufous • Butterflies • Migrate from south during spring • Monarch and Eastern Tiger Swallowtail • Habitat: warm and dry, protection • Massed planting of one type • Caterpillar food plant • Weedy plants host to species • Heights • Food source: nectar
Background • Contribution to the ecosystem • Biodiversity • Lost due to alteration of habitat, species in surrounding area, and climate change
Background Ruby-throated Eastern Tiger Swallowtail Rufous Monarch
Background • Wildflowers • Attract both hummingbirds and butterflies • Source of food and protection • NJ climate • Growing season • Warm and dry • Warm days, cools nights
Ethical Issues • Responsibility to care for environment • Need resources, but also need to give back • Give protection to species • Conserve
Objectives • Purpose: bring butterflies and hummingbirds to BTHS • Observe and record species • Flowers, hummingbirds, butterflies • Observe what plants species are attracted to • Effects of solution • Advantages • Habitat for species • Biodiversity • Observing nature
Rationale • Landscape designs to conserve species • Sites with greater diversity of habitat types and more varied terrain tend to have butterfly populations that are more stable over time • Woodland, grassland, heathland • Become adaptable • Change in climate • (Centre for Ecology & Hydrology, 2010)
Rationale • Evolution of columbine flowers in North America • Red, white, yellow • Plant population shift • Hummingbird-pollinated red flowers • Hawkmoth-pollinated white or yellow flowers • Natural selection to change flower color • (University of California - Santa Barbara, 2009)
Rationale Evaluate impact deer grazing can have on nest quality and food resources of birds Decline of forest birds Disease, loss of habitat and increase in number of animals that prey on bird nests (Staedter, 2005)
Site Selection • Area • Moisture • Water-accessible • Drainage • Percolation tests • Sunlight • Warm days, cool nights • Practicality • Away from sports • Visible from basketball court
Soil Quality • pH • Composition • Minerals (Chlorine, zinc) • Clay, sand • Moisture, drainage
Soil Classification • Based on proportions of silt, sand, and clay
Materials • Meter sticks, accurate to the nearest 0.1 m • Shovels • Rakes • American Meadows™ Butterfly & Hummingbird Seed Mixture, 1 lb. ($24.95) • Buckets • Sand • Hose (water) • Scarecrow (optional)
Seed Mixture • Wildflowers – extremely adaptable • Mix of perennial + annual blooms • First year • Sprout: ~2 weeks (8 days – months) • Bloom: 3-4 weeks after sprouting • Annual blooms • Following years: • Heavy perennial bloom + reseeded annual bloom • Store in cool, dry place (5 years)
Preparing the Soil • Spring • Clear area of all existing growth • Particularly old roots - competition • Till ground • Turn soil, rake area flat
Sowing the Seeds • Next day • Windless • Amount • 1 lb. for 2,000 - 3,000 square feet • Up to 3x minimum coverage rates • Too dense inhibits growth
Split & Sand Method • Divide seed mixture in half • Add 10 parts sand • Hand-sow • Repeat • Advantages • “Dilute seed” • Avoid missing areas
After Sowing the Seeds • DO NOT rake or cover with soil • Compress seeds into soil • “Seed to soil” contact • Scare birds (optional) • Keep soil moist for 2-4 weeks • Weed by “clumping” • (American Meadows™, 2010)
Maintenance of the Meadow • Annual responsibilities: • Late fall: leave garden as is • Allows for any butterflies in egg, caterpillar, or chrysalis to survive winter • Reseed annual blooms (optional)
Data Collection • Observe and record types of plant growth and animal species • Photograph • Identify and classify species • Randomly select 10 plants of each type to measure average heights • Plot scatterplot of number of butterflies or hummingbirds attracted to specific flowers • To plan for future – which plants to reseed
Timeline • Monday, March 8 • Place order (5 business days) • Tuesday, March 16 • Till land • Wednesday, March 17 (after school) • Sow seeds • Thursday, March 18 – Thursday, April 1 • Water area, weed • Thursday, April 1 – Thursday, April 29 • Record types of flowers, plants, animal species
Implications • Drawbacks • Requires maintenance • May decrease insect populations • Cost • $24.95 for seeds • Fundraising to decrease cost
Groups • Education • Raise awareness • Asbury Park Press for publicity article • “Construction” • Organize ordering of and gathering of materials • Coordinate maintenance of meadow
Fundraising • Contact American Meadows™ • Write to PSFA • Write to local botanists or NJ planting agencies • Host fundraiser • Sell plantable paper
Fundraising • Eco-Calendar • Plant pages
Conclusion • Benefit outweigh costs/effort • Garden will: • Increase biodiversity of flora and fauna • Increase aesthetic appeal of area • Costs: • Work • $30.00
Thank you very much. Any questions?
