lab 10. pre-lab
In this week's lab, you will be introduced to ecology and some important ecological principles. You will explore different types of high-impact (or especially important species) like apex predators and ecosystem engineers. You will read over the KY Wildlife Action Plan, which uses ecological principles to manage natural resources across our state. You will use data from across Kentucky, and your knowledge of high impact species, to determine priority areas for conversation.
What is ecology?
Humans are the dominant force on this planet. How we manage our natural resources dictates the health our environment. The principles of ecology are used by agencies and non-profit organizations to manage resources using best practices in order to maintain a healthy and functioning biosphere. Ecology is the study of how organisms interact with each other and their environment, and a primary goal of ecology is to understand the distribution and abundance of organisms. There are several levels of ecological study from organismal, to that of the population, community, ecosystem and globe. Each level can be synthesized and applied toward conservation biology.
Types of ecological study listed in hierarchical order.
Conservation biology is the effort to study, preserve, and restore threatened genetic diversity in populations, species diversity in communities, and ecosystem function. Understanding ecological principles is vitally important in prescribing conservation efforts. One such effort is common across every state. It is called the "Wildlife Action Plan." These plans collect species abundance data from across the state, as well as habitat data, in an effort to make ecologically-based decisions regarding management of the state's wildlife resources. These plans are intended to work at the landscape level of ecology. Kentucky's Wildife Action Plan was written in 2013 by the Kentucky Department of Fish & Wildlife Resources. It will be revised soon, in 2023. Kentucky Department of Fish & Wildlife Resources is an agency of the Kentucky Tourism, Arts and Heritage Cabinet and it is responsible for the conservation of wildlife resources and for boating projects in the state.In this week's lab, you will use data collected from across the state to make recommendations for the plan's revision.
Do you know enough about high impact species?
We know that each species oppies a unique niche and plays an important role in their ecosystem. However, some species carry more weight. We can refer to these species as high impact species, those with especially vital ecological roles (e.g., predators) or special designations making them a greater conservation priority (e.g., threatened) or threat (e.g., invasive species). Look over the nine key categories of high impact species below. As you look over your data during the lab, you may want to use these species types in making your priority or funding recommendations.
|
Keystone Species
Species on which other species in an ecosystem largely depend, such that if they were removed the ecosystem would change drastically. 
Eastern hemlocks are a KY keystone species; they provide shade which lowers stream temperatures, and valuable refuge for migrating birds. They are current under threat from the hemlock woolly adelgid, an invasive insect.
|
Apex Predators
Predators at the top of a food chain, without natural predators of its own. They often control the abundance of other species. 
Bobcats have been scarce in KY since the 70s but are making a rebound and can now be found in most counties. The are secretive and illusive. They help control populations of rodents and rabbits.
|
Ecosystem Engineers
Organisms that directly or indirectly affect the availability of resources by causing physical state changes in biotic or abiotic materials. 
Beaver dams can drastically alter the geomorphology of streams, rivers, and lakes across KY. Their dams create large pools that are used as important refuges for fish, amphibians and migrating waterfowl.
|
|
Native (Indigenous) Species
Species are considered native to the region if their presence is solely due to natural circumstances (evolution, dispersal, and migration). 
The Great Blue Heron is KY native and commonly spotted alongside our lakes and river. They have bounced back after steep declines in the 70s. While compact when standing on the shore hunting, the birds elongate in flight.
|
Endemic Species
Species that are geographically restricted to certain locations and do not occur naturally in other part of the world. 
The relict darter is a rare species of freshwater ray-finned fish that is endemic to a single small watershed in KY and only exits in two counties. KY is well-known for housing many endemic dater species.
|
Threatened or Endangered
These are species whose population numbers are dangerously low. Endangered species are closer to extinction than threatened species. 
The Indiana bat is endangered in KY and federally. Decreases in Indiana bat populations have been caused by several factors, most of which are the result of human activity (e.g., altering cave entrances).
|
|
Migratory Species
Species in which all or part of the population emigrate regularly, periodically, or seasonally from a geographical area to another. 
Neotropical migratory birds breed in Canada and the US and spend winter in Mexico, Central America, South America or the Caribbean islands. The indigo bunting, a KY migratory resident is pictured above.
|
Exotic or Introduced Species
A species that is not native and has been accidentally or deliberately transported to the new location by human activity. Many become invasive. 
Multiflora Rose was introduced for landscaping in KY. It forms impenetrable, thorny, thickets in pastures, fields, and forest edges. It restricts wildlife movement and displaces native vegetation.
|
Invasive species
A species that becomes overpopulated causing ecological, environmental, and/or economic damage. Most are exotic/introduced. 
Zebra mussels are an invasive, fingernail-sized mollusk that is native to fresh waters in Eurasia. They compete with KY-native fish and invertebrates, particularly our diverse and endemic mussel populations.

What is the Kentucky State Wildlife Action Plan?
Kentucky’s state wildlife action plan summarizes the status of our state’s more vulnerable wildlife species and the condition of habitat on which they depend. It is a blueprint to drive conservation priorities and decision-making, developed by partners and approved by the U.S. Fish and Wildlife Service. Actions plans are adaptive: regularly reviewed and updated to keep current with emerging wildlife issues. The plan was written in 2013 by the Kentucky Department of Fish & Wildlife Resources, an agency of the Kentucky Tourism, Arts and Heritage Cabinet, and will be reviewed every 10 years. Why is it important? To maintain the health and diversity of Kentucky’s fish and wildlife resources, we must prioritize projects and direct limited financial resources where they are most effective. Strategies, therefore, often include management of rare/endangered species, those that are in decline, and many that have received less attention in the past. Because recovery is more costly and difficult to achieve once a species is imperiled, the goal is to intervene before a species is in crisis, to keep common species common, and ensure healthy resources for future generations of Kentuckians. What species are included? Kentucky’s current plan identifies 301 species in greatest conservation need, including freshwater mussels, fishes, crayfish, songbirds, reptiles, turtles, amphibians, and mammals. These designations include many of the high impact species discussed in the pre-lab: keystone species, apex predator's, migrants, ecosystem engineers, endemics, natives, and threatened and endangered species. During the revision process, species specialists evaluate new information to keep this list current. They also consider ongoing and new environmental stressors and identify specific conservation efforts necessary for recovery of these species and their associated habitats. Priority Habitats
Kentucky's Species of Greatest Conservation Need (SGCN) 301 species were identified as particularly important for conservation efforts An example in each taxa is below. -Excerpts from the Kentucky Department of Fish & Wildlife Resources |

Exercise II. conservation priority ARea DeterminationAs you may have gathered, it is not possible to equally conserve all areas of the state equally and simultaneously. Much of the state is already developed, and it is not financially feasible to protect all the remaining hectares. Instead, the state has been divided into Priority Conservation Areas (or PCAs, see Appendix 4.26 below). These Conservation Areas have been ranked in importance (based on overlap). The Tier I areas (in red below) were identified as the most important areas to conserve in the state. All Tier I Priority Conservation Areas combine to comprised 14.4% of Kentucky’s total land area but contain occurrence records (sightings) for 91% of all SGCN. These figures are in agreement with United Nations guidelines for reserve design that gives a target of 12% land area encompassing 85% of targeted species.
Today, you will use the provided resources (from the KY Department of Fish and Wildlife), to compare and contrast these three conservation priority areas. Procedure.
