Aldo Leopold (1948) “ A thing is right (good) when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong (bad) when it tends otherwise. “

People have changed the landscape
Up to 85% of the Earth’s surface has been altered by people- we have had a tremendous impact on the environment.

People have changed the landscape
Up to 85% of the Earth’s surface has been altered by people- we have had a tremendous impact on the environment. Ecosystems are constantly adjusting according to rapidly changing conditions.

Manitowoc County Bordered by one of the largest lakes in the world Manitowoc County has more than 50 lakes not including unnamed lakes and springs
7
Manitowoc County Lakes
Provide much needed habitat for nesting and migrating birds of all types- waterfowl, raptors, songbirds, etc. Open water, emergent aquatic, and different shoreline wetland habitats each contribute important benefits to many types of wildlife.

Loons
24
Loons in Wisconsin There are about 4,000 loons in Wisconsin, compared to about 3,000 in the year 2000. Prefer to nest on lakes with irregular shoreline, native vegetation, good water clarity, not too much human disturbance. Loons “imprint” on the lakes on which they were hatched, and return there to nest when adults. Most males within 7 miles, females within 15 miles.
25
Loons Young loons return to the region where they were hatched at age 3, but may not actually find an open nesting territory until age 6. Loons can live for 25 years in the wild. Lakes in Manitowoc County provide migratory stopover habitat, which can be crucial for loon survival.
26
Loons Loons begin migrating south in October, moving first over to Lake Michigan in stages, then to the south end of the Lake, then in November fly in 1-2 days from there to the Gulf of Mexico. Young loons migrate north their first spring, but along the Atlantic coast to the Gulf of St. Lawrence. Then back to the gulf for winter.

Improving Backyard Habitat
55
Food, Water, Cover
56
Food Many native plants provide food for birds and other wildlife- from coneflowers to choke cherries to oaks. Don’t forget nectar plants for pollinators Milkweed for monarch butterflies Possibilities are endless depending on goals
57
Food Cont’d Native plants can provide not only fruit but also harbor insects eaten by wildlife Fewer insects on cultivars or non-natives Native plants are often easier to maintain Migratory birds seek insects (from water) in spring, and fruit in fall
58
Water As simple as a birdbath Sound of flowing water attracts wildlife
Shallow, gradually sloping edges so animals don’t drown
59
Cover Shrubs/trees with dense foliage, some evergreens
Select plants that deer don’t like, or be prepared to protect them
60
Putting it all together

Shoreline Habitat Enhancement

References How to Manage Your Land to Help Birds
By Vicky Piaskowski- free online Birdscaping in the Midwest by Mariette Nowak National Wildlife Federation Backyard Habitat Program
65
Final Thoughts There are about 300 species of birds that can be seen in and around our lakes. The lakes and the land around them are inseparable, and both should be appreciated and sustainably cared for.
