Florida Key Deer(Odocoileus virginianus clavium)

Lives only in the Florida Keys

Sub-species of the white-tailed deer

Migrated over a land bridge during the Wisconsin glaciation

Earliest documented migration in the 1550s

Listed as an endangered species

Hunted for food supply

Banned in 1939

Population has risen since 1955

Our Goal

Determine potential, private, undeveloped land for acquisition using a GIS

To find a suitable habitat for the Key Deer population

Based on popular vegetation for the species

Away from major roads

This is where most deaths occur

Projection Requested Contiguous Albers Equal Area Conic

Central Meridian: -84.0

1st Standard Parallel: 24.0

2nd Standard Parallel: 31.5

Reference Latitude: 24.0

False Easting: 400015

False Northing: 50.0

Mapping the Area

Add data provided

Vegetation

Mortality

Ownership

Ensure that all layer are correctly projected

Use the Contiguous Albers Equal Area Conic

Initial Map

Vegetation Map

Adding the Telemetry Points

Convert Telemetry locations .dbf to .shp

Add data –> add XY data -> edit

Project to NAD_83

Export data as a shapefile

A cluster of points will appear off of the map as shown below

Define and Project the Telemetry Points

Use the Define Projection tool

Use Contiguous Albers Equal Area Conic

Project tool

Use this tool to project the telemetry points to align with the other layers

Set output to North_America_1983

Mapped Deer Telemetry Points

Joining Relevant Points

Use the Spatial Join tool to join the telemetry data with the types of vegetation

This allows you to select telemetry points according to where they were found in each type of vegetation

Fill in the table provided

Calculate the expected amount of observed deer

Ratios are calculated and show preferred vegetation

Pick two forms of preferred vegetation

Hammocks and Pinelands were used in this project

Create a Preferred Vegetation Layer

Select Pinelands and Hammocks in the vegetation layer

Export this data to create a layer that shows only the preferred vegetation

Dissolve tool

Use this to dissolve unnecessary data

Multipart tool

Use this tool to keep data for each polygon in the preferred vegetation

Pinelands and Hammocks

Add Road Data

Convert e00 file to shapefile using the Conversion tools -> to Coverage

Select the major roads

Highway 1 and Key Deer Boulevard have the highest mortality rates

Create a Buffer

Creating a buffer will keep these areas out of your selection

30 meter buffer for highway 1

50 meter buffer for Key Deer Boulevard

Merge the buffers into a single buffer

Roads

Map with Road Buffer

Selecting an Area for the Habitat

Selecting an area

Away from human activity

Close to federal land

Outside of the buffer zone

Close together if multiple parcels

Selected multiple parcels

Total acreage: 4.11 acres

Determining the Cost

Determination Factors

Total acres of undeveloped land: 1217

Total cost of undeveloped land: $28,924,293

Cost per acre

Total cost/Total Acres

$28,924,293/1217

Cost per acre = $23,766.88

Selecting this location

Selected on these factors

Total cost: $97,173

Total acreage: 4.11

Proximity to federal land

Gives a better chance for expansion

Protects land from future development
