Northern red oak (Quercus rubra)


Plant Family: Beech (Fagaceae)
Project BudBurst Plant Group: Deciduous Trees and Shrubs

Identification Hints: Northern red oak trees are foundthroughout the eastern United States, as far west as Kansas and as far south asGeorgia. These trees can grow to up to 140 feet tall. The leaves of Northern red oaks have 7-9 pointed lobes with v-shaped sinuses (the indented part between the lobes). The bark of the Northern red oak is distinctive. It has dark red to grey-brown ridges with what appear to be shiny stripes down each ridge.

Did you Know? These trees have separate male and female flowers that appear in the form of catkins. Both male and female flowers can be found on the same tree. Acorns develop after the flowers have been pollinated but do not reach maturity (ripening) until the second year. Northern red oaks have been used in many revegetation projects following coal mining. The lumber from Northern red oaks is also commonly used in furniture making.

The table below displays all the data that has been submitted to Project BudBurst. By default, the data is sorted by the date on which the phenophase occurred. Clicking the up and down arrows next to each column name allows you to sort on any value. If there have been more than 10 observations submitted, you can choose how many to display at a time using the "Show __ entries" control. You can also page through the data using the previous and next buttons at the bottom right of the table.

The Search box allows you to search all of the data. Searching by date, species, phenophase, etc. is easy—just start typing and the table will immediately change to contain only observations that contain your search phrase. Do you want to see only 2012 observations? Just type "2012" in the search box. Only want to see maples? Enter "Acer." You can combine searches, too! Searching for "acer 2012" will narrow your results to only the maples that were observed in 2012 (assuming that any observations exist, of course).

Once you have your results in the order desired, you can use any of the buttons above the search box to copy the results to the clipboard; save them as a text, or spreadsheet; or even print them from your browser!
