Since the original Tampa Tree Map was released in 2013, the technology has evolved!
The new look reflects many improvements in the underlying technology, making the Map tablet-ready, easier to use, faster and more flexible. We’ve also linked the Tampa Tree Map to the larger OpenTreeMap community, so we’ll see new features regularly and better bug fixes. These new features include new Apps for both iPhone/iPad and the Android devices. Visit the Apple App Store or Google Play and search for OpenTreeMap.
Don't worry! We greatly appreciate the work you've done, and we've preserved all the data entered by users like you. All of the information you have entered is part of the new version, except in those areas were professional urban foresters have updated the trees. We hope you’ll keep contributing! We’ve switched to a new platform, so you’ll need to create a new account.
There are several ways that you can explore and use TampaTreeMap.
Thank you for your assistance in making TampaTreeMap a great resource for information on trees in the City of Tampa and the greater Tampa bay region!
Visit the Tree ID link at the bottom of the page, or check out other tree identification resources on the Resources page. Tree identification is a skill that takes time to master, and usually a lot of training. Therefore, rather than guess the tree species, you can still add your tree to TampaTreeMap by choosing “unknown” as the species. You can still provide valuable information about the size of your tree. You can then upload images of your tree and its bark, leaves, flowers, or fruit and perhaps other TampaTreeMap users will be able to determine the tree species based on these images.
Entering the diameter of a tree is crucial for helping track that tree’s growth and environmental benefits. Measure the diameter or circumference of your tree to the nearest inch. Circumference is easier to measure and will be automatically converted to diameter). Circumference can be easily measured by wrapping a cloth tape or string around the tree at breast height (approx. 4.5 ft) perpendicular to the lean of the tree. If there are branches or other projections place the tape above them. If a fork appears well below 4.5 ft., you will need to measure each trunk. When using the website, you can add additional trunk measurements on the edit info page for your tree.
The following video from the people at UrbanForestMap.org provides a quick tutorial on an easy way to measure your tree’s diameter.
Foresters use specialized tools when measuring tree height, such as a clinometer, a Biltmore stick, or a laser hypsometer or rangefinder. These devises use trigonometry to determine the tree height based on distances and angles.
There are a couple of other less accurate, but simple methods you could use to estimate the height of a tree. Here is a simple way to estimate the height of a tree. You will need two people for this activity. You also will need a yardstick, notepad and pencil. Be careful! This procedure involves walking and looking at your tree. Always look where you are walking and be careful near roads.
Example: Jennifer and Mike are measuring the height of a large live oak tree on their school grounds. Jennifer measures the apparent height of the tree to be 34 inches, and the apparent height of Mike to be 7 inches. Mike’s actual height is 5 feet (60 inches). To determine the actual height of the tree, Jennifer and Mike solve for X = (34 inches / 7 inches) * 60 inches = 291 inches / 12 inches = 24 feet
Tree condition requires a trained eye to evaluate. However, there are two categories anyone can identify. If a tree has been removed, or is otherwise missing, select REMOVED. If the tree contains no living parts, no leaves, and is completely dead, select DEAD. Note: a tree with any minor living components, however small, should not be marked DEAD. Noting these two conditions will help us track the loss of trees. If you are interested in specifying other conditions, consider going through one of our training programs.
The canopy condition is an estimate of the fullness of the tree's canopy. This information is optional and generally used only by experience foresters. If you wish to include the canopy condition, use the guidelines below to evaluate the condition of the canopy of your tree. Select one of the options from the dropdown list that bests describes the amount of gaps in the tree canopy. Visualize the expected/idealized outline of the tree canopy, taking into account the natural canopy shape for the particular species. Now estimate the percent of foliage that is absent due to pruning, dieback, or defoliation. This information allows TampaTreeMap to calculate the ecological benefits of the tree canopy.
The Planting Site is the location of location where the tree is planted. The planting site might be a rectangular cutout in a downtown sidewalk, or it might be an open area of a backyard. There are a number of different types of planting sites that you can define by choosing the appropriate plot type on the tree details page. Please select the one that most accurately reflects your tree's location. If you are unsure, leave these measurements blank.
Enter a measurement of the length and width of the planting site in feet. If you are unsure or do not have means to measure the plot, leave these measurements blank.
Answer yes, no, or unknown to whether there are power lines overhead within a distance of 10 ft. from the base/trunk of the tree. Exported data uses the values 1=yes, 2=no, 3=unknown, and 0 or NULL (depending on how you exported data) was left blank.
Look to see if tree roots are lifting nearby sidewalks. Check either “minor or no damage” or “raised more than ¾ inch” to indicate the condition of a sidewalk within 10 ft. of your tree
The planting site stewardship is where experienced users can enter information about actions taken to modify the planting site where the tree is growing. For example, City staff might enter the date when they enlarged a rectangular planting well/pit in a sidewalk.
Tree stewardship includes actions to care for a specific tree. The tree stewardship information in Tampa Tree Map is a location where you can keep track of activities such as when you pruned a tree, or mulched around the tree, or even when you watered a tree. This information is entirely optional, but can be a useful way to keep track of all the things we do to care for trees.
There are a number of great ways to get involved in caring for trees and supporting conservation events throughout Tampa. Look for links to those organizations coming soon.
Currently the TampaTreeMap is only intended to document trees within the City of Tampa. This is because it cost money to maintain the tree map website and we would need additional funding to expand the tree map. If you are interesting in establishing a tree map in your community, please contact us by using the TampaTreeMap contact form.
If you are from a town or other community and have a tree inventory you would like to add to TampaTreeMap, please contact us by using theTampaTreeMap contact form.
TampaTreeMap is designed to collect tree data by crowdsourcing. In other words, it allows YOU and other members of your community to create an inventory of trees and learn about the benefits that trees provide. The data is only as good as you make it. You can help us ensure that the data is as current and accurate as possible by updating and correcting information on the trees in your neighborhood.
Some of the data comes from horticultural organizations who have carefully surveyed street trees throughout the city. Other data comes from City staff who use the TampaTreeMap as a tool to manage trees. We have implemented a number of checks that will hopefully prevent the entering of incorrect data. If you find incorrect information, please correct it!
TampaTreeMap is a collaborative mapping tool and inventory of trees in the City of Tampa. It is not a tool for reporting issues with trees or potentially hazardous or dead trees. If you are concerned about a public tree, please contact your local government. In the City of Tampa: Tree Emergencies: (813) 274-5744 (blocking streets and sidewalks) If you are located outside the City of Tampa bay, please contact your local government to determine the best way to report tree issues.
To calculate the eco impact of a tree, the iTree software we use must know the species and diameter of the tree. For many of the trees, we might know the location of the tree but not the exact species and diameter. For this reason, many neighborhoods in Tampa bay may show lots of trees but not list any eco impact data. You can help us more accurately calculate eco data by entering the species and diameter for trees in your neighborhood.
We calculated the economic benefits and environmental impacts of the trees using the i-Tree software provided by the USDA Forest Service. This software provides options for calculating benefits by assigning a dollar value to the impact of trees in a number of ecological areas. These areas include electricity, natural gas, carbon dioxide, particulate matter, nitrogen dioxide, sulfur dioxide, volatile organic compounds, and stormwater interception. The USDA Forest Service provides default dollar values for each of the categories in iTree. We used these default values for carbon dioxide, particulate matter, nitrogen dioxide, sulfur dioxide, volatile organic compounds, and stormwater interception as no values specific to the Tampa Bay region were available. For the electricity fields, we used a prices based on local Tampa Bay electricity rates for residential customers. To calculate the benefits to a homeowner, we also entered a median home sale price for Tampa Bay. Based on these numbers, i-Tree calculated the approximate financial benefits of a tree based on its species and size.
