Geog 111: Part 2

-70% canopy closure, dominated by trees

-Categorization system used before Linnaeus system, based on descriptions

• -binomial
• -breaks into groups like family, genus & specie

• -Genus is always capitalized
• -species is never capitalized
• -based on reproductive characteristics, not descriptive characteristics
• -when writing scientific name, always underlined or italicized
• -family ends in aceae

Present on the exterior of trees

Leaves on some plants, set together in a bundle- by looking at how many needles are in a bundle-you can determine the type of pine

-one blade

-has many small leaves that make up a whole leaf

• 
• -Occurring in pairs at the same level on opposite sides of the node; 2 per node

Leaves are in an alternating pattern

• -sap that comes out of tree when tree is damaged
• -Rubber is made from latex
• --can be different color based on species like yellow, red, black, white, etc.

• -appendage at the base of leaf that was where leaf emerged
• -covered up leaf before it popps out

• -Flavor Crystals
• -looks like holes
• -Ex. Citrus leaves and Eucalyptus trees

• --some plants have glands & produce waterfalls of nectar to attract protectors (like army ants) to prevent other animals to mess with them... maybe also pollinators?
• -common in the pea family

• -evergreen: keep their same color and leaves throughout the entire year
• -deciduous: leaves fall off and die in the winter

• -Humans release a lot of c & co2 in atmosphere, understanding how much is stored in forests (carbon sequestration) is used in carbon credits, climate models, etc.
• -understand forest productivity/health
• -intrinsic value
• -timber value, successional stages, fire fuels, biodiversity & habitat, etc.

• -Create hectare plots (100m x100m),
• -measure every tree greater than 10,000m2, core tree for wood density.
• -Higher density = higher storage of carbon,
• -lower density = lower storage of carbon

• -Tropical Dry Forest: occurs in tropical forests on leewards side of mountain ranges (in rain shadow),
• -will experience periods of low rainfall (dry season) every year

• -find known locations to predict where it occurs now/future,
• -create a model to find out where it is best to plant, go plant it!
