\"Fall<\/a><\/p>\n

“Life starts all over again when it gets crisp in the fall.” -F. Scott Fitzgerald<\/em><\/strong><\/p>\n

Fall officially kicks off Saturday, September 23, 2023\u2014the same day as the autumn equinox\u2014in the Northern Hemisphere. Many of us in Maryland are looking forward to leaving behind the days of record-breaking heat and welcoming clear, blue skies, cooler evenings and autumnal tree canopies. The Maryland Department of Natural Resources once again will present its weekly Fall Foliage Report, posted online<\/a> and sent by email bulletin to subscribers<\/a>. <\/span><\/p>\n

What can we expect from fall foliage this year and when can leaf peepers catch a glimpse of fall\u2019s best colors?<\/span><\/p>\n

What the Science Says<\/span><\/h3>\n

For years, scientists have worked to understand the changes that occur in trees and shrubs during autumn, according to the <\/span>United States Department of Agriculture Forest Service<\/span><\/a>, but they can agree that three primary factors influence autumn leaf color: leaf pigments, length of night, and weather.<\/span><\/p>\n

Maryland Department of Natural Resources State Forest Manager Melissa Nash explains. \u201cDuring the warmer summer months, leaves are green due to the chlorophyll pigment. Along with that green pigment are hidden yellow to orange tones called xanthophyll and carotenes (these are the same type of pigments that give carrots their orange color).\u201d\u00a0<\/span><\/p>\n

But what causes the transition from green to shades of orange, yellow and red? Nash points to the length of daylight and cooling temperatures characteristic of fall months.<\/span><\/p>\n

\u201cAs fall approaches, changes in the length of daylight and decreasing temperatures cause the leaves to stop their food making process of photosynthesis. When this happens, the chlorophyll breaks down and the green color begins to disappear, revealing yellows and oranges. Around this same time, some trees also produce pigments called anthocyanins which cause red to purplish tones.\u201d<\/span><\/p>\n

So when can we expect to see the leaves start to change in Maryland? <\/span>The Department of Natural Resources\u2019 foresters offer their expert predictions, beginning with the state\u2019s westernmost counties.<\/span><\/p>\n

\u201cThe early leaf out and long summer dry weather will negatively impact fall foliage in western Maryland, particularly Frederick and Washington counties. Here in western Washington County the Fairview Mountain ridge is displaying some color, but unfortunately it is the result of leaf drop from drought stressed trees (as pictured in the below photos from Indian Springs Wildlife Management Area, showing “fall” color on the ridge, early leaf change of black walnut, flowering plum, and linden).\u00a0 In Frederick county, most of the black gum and sweet birch have already lost their leaves due to drought stress; they did change color, but leaf drop immediately followed.\u00a0 A well timed tropical storm could help offset drought conditions, but will likely not reverse the\u00a0 impacts of drought stress to fall color from an entire growing season of drought conditions.\u00a0 Time will tell though, as the oak dominated ridges are normally hitting peak in the latter half of October.\u201d<\/span><\/p>\n

\u201cIf we don’t get some rain, I don’t think it’s going to be a spectacular year like we had last year. Hot and dry just doesn’t bode well for fall color. We are already starting to see a few subtle hints in Garrett County.\u201d<\/span><\/p>\n

\u201cThe canopy throughout Patapsco Valley State Park is starting to look a little more bare than it normally would this time of year due to the heat and lack of rain this summer. With that said, we still have quite a few indications that the beautiful Autumn foliage has not given up on us!\u201d<\/span><\/p>\n

\u201cFair Hill Natural Resources Management Area is located in an area which was affected by drought earlier in the summer. Trees susceptible to drought like black walnut are showing telltale signs, with leaves beginning to fade to yellow. The leaves of tulip poplars are turning yellow with crisp brown edges; their leaves have been dropping for some time. Due to the conditions described and the warm weather, we predict a below-average display of autumnal foliage in the area.\u201d<\/span><\/p>\n
