Austin's seeing brighter leaves this fall, thanks to recent rainfall.<\/p><\/div>\n

Think of fall\u2019s turning leaves, and Texas may not be the first state to come to mind. But Austinites have seen their fair share of autumnal red and gold this year \u2013 thanks in large part to recent rains.<\/p>\n

Jerry Brand, a molecular bioscience professor<\/a> at the University of Texas, says the color changes in the leaves are due to a specific molecule called a carotenoid<\/a>.<\/p>\n

\u201cThese color molecules called carotenoids can come in several different colors depending on the plant, depending on the light intensity they\u2019ve been exposed to, and other environmental factors,\u201d Brand says.<\/p>\n

<\/p>\n

\u201cSo that\u2019s why some leaves look more yellow in color, some look brilliant red in color and some look more orange in color,\u201d he continues. \u201cIt\u2019s because there\u2019s more categories of these carotenoids, and which ones are dominant depends on the plant species \u2013 and that also depends on the environmental conditions they\u2019ve been exposed to.\u201d<\/p>\n

One environmental condition defined Texas lately: drought. In a drought, leaves conserve water and fall off early to avoid too much evaporation. That\u2019s why recent years haven\u2019t featured much fall foliage.<\/p>\n

But Central Texas\u2019 glut of rainfall in the last two months has improved the health of many of trees in Central Texas \u2013 and that\u2019s led to a more colorful fall.<\/p>\n

\u201cPlants can respond very quickly to changes in the environmental condition,\u201d Brand says. \u201cIf the drought disappears, then the molecules start building their leaves stronger and making them function better in a matter of weeks, or even less.\u201d<\/p>\n

The drought is far from over: portions of Travis County are still in moderate drought. You can see statewide drought conditions here<\/a>. But in Austin, drought stricken trees have had time to rebuild their color molecules making their leaves brighter and more vibrant.<\/p>\n

Brand says fall foliage in Texas peaks about a month later than northeastern and northwestern parts of the country. Trees with the most lively colors are Sumacs, revealing a bright red pigment, and Native Elm Trees, exposing a vivid yellow.<\/p>\n

Texas Parks and Wildlife<\/a> says one great park for fall foliage is just a day trip away: the Lost Maples Natural Area<\/a> in the Hill Country.<\/p>\n","protected":false},"excerpt":{"rendered":"
