Trees of Florida
At the Trees of Florida station, participants will be asked to identify tree specimens presented indoors on tables. Juniors will be asked to identify 15 trees, Intermediates will be asked to identify 20 trees, and Seniors will be asked to identify 30 trees. Participants will not be asked for scientific names, or about any of the natural history information at the Tree ID station, but some of that information may be useful in the Forest Ecosystem station.
The way that participants will record their answers depends on the age classification. Juniors and Intermediates will be given lists of possible trees in alphabetical order by common names, and will be asked to match the number for the tree name with the letter for the sample on the table. Seniors will not receive a list of names. They will only receive an answer sheet with blank spaces, and they will need to write out the common name for each sample. Spelling, including capitalization, must be the same as that on the Official Tree List in order to be counted correct. The Official Tree List is the chart below. Please note that the only capitalized words are proper nouns, like American, Florida, and Brazilian. All other parts of plant names are lower case. Also please pay attention to which words are separate and which are merged. Redbay is merged because the tree is not in the bay family. Red maple
is separate because it is a maple. Bald cypress is spelled baldcypress on some lists, but we are making it separate. Minor spelling errors (including capitalization) will result in ½ point per tree.
Participants are encouraged to practice using the actual scoresheets for the contest. Students who request assistance with reading or writing will be put in Group E, where points will not be deducted for spelling errors.
Identifying Tree Species
The majority of the tree species for Seniors are also on the National 4-H Forestry Invitational list, which should make it easier for Senior participants to study for the national contest.
To prepare for this station, participants should study the chart below, paying close attention to the trees marked for their age group. Participants must be able to identify those trees by leaf, twig, or fruit. Select the common name of each tree to learn more.
In addition, several introductory videos are available to help youth get started with tree identification.
- Tree Identification for Juniors
- Tree Identification for Intermediates
- Tree Identification for Seniors
Duval County 4-H also created a series of video tutorials on Trees and Plants of Florida.
Finally, the videos below provide information and tips on leaf arrangement, composition, and parts of a leaf.
Note: Highlighed trees are considered invasive to Florida.
