Rationale of Choosing the Blue Heron Nature Preserve

For my project, my study area will be the Blue Heron Nature Preserve in north Atlanta, Georgia. The nature preserve includes the 3-mile Blueway Trail within 30 acres of the nature preserve; the preserve is made up of meadows, woodlands, wetlands and riparian. They have over 28 plant species and over 35 animal species, so I think it gives a lot of opportunities for investigating and documenting the biodiversity. The nature reserve also promotes certain aspects of each area: the meadows promote reintroduction of pollinators, the woodlands promote proper burning of firewood to reduce tree disease, the wetlands promote the importance of water quality and the riparian promotes runoff education. The are also has over 13 research conservation projects, including a turtle sanctuary, rain garden, Neighborhood Water Watch program and the Field Research Center Native Pollinator Garden. I think the Blue Heron Nature Preserve has a lot of opportunity to be a great source of information for this pro...

Audubon Bird Guide Review

Image
 This week, I reviewed the Audubon Bird Guide in relation to the Blue Heron Nature Preserve. When I first opened the app, I liked that it had the Get to Know 20 Common Birds guide. As someone who is not too familiar with the birds in my area, it was nice that the app allowed beginners to get a good footing in bird sightings. On the main page of the app, it also has the capability to identify a bird by characteristics (size, color, type, activity, habitat, voice, wind shape and tail shapes) or by searching the bird's name in the guide. This allows beginners and experts to identify birds based on their own skill sets. On the Explore page of the app, the map allows you view Hotspots  with pings of recent bird sightings in the area. The Agnes Scott College Hotspot (below) shows the date, time, species and amount of sightings. I like that the sightings show clear images that would make it easy for me to start recognizing these birds in my neighborhood.  If you press on one of ...

My Definition of Biodiversity and Importance of Biodiversity

 To me, biodiversity is the study of the vast array of plants, animals, and microorganisms that makes up an area and promotes resiliency in an ecosystem. When thinking about biodiversity on a local and regional level, it provides a unique chance for unity within a community. Species that only reside at local or regional levels can cause the community to take accountability for the species, because they feel the need to protect it. These endemic species make a community more unique and could result in more protection and conservation efforts. Biodiversity is important nationally and internationally because it supports medicinal demands, climate regulation, and basic human needs; biodiversity also holds the power to grow and expand into something new as the Earth and its inhabitants evolve. On a strictly national level, a diverse biodiversity has the ability to allow the country to flourish as long as the inhabitants of the country know how to work with the biodiversity and not again...
