A late holocene pollen sequence from Aronow Bog, northern Harris County, Texas Academic Article uri icon

abstract

  • The analysis of fossil pollen, spores and charcoal from 1.15 m of sediments deposited over a period of more than 1,000 years at Aronow Bog in northern Harris County, Texas is the first detailed record of the paleovegetation from southeast Texas. Prior to 1010 YBP, low amounts of arboreal pollen along with abundant grass and herb pollen suggest that this now-forested area was open grassland. Between 1010 YBP and 170 YBP an increase in oak pollen combined with a continued abundance of grass pollen suggests that the area was an oak savanna. In addition, increases in charcoal suggest a higher frequency of forest fires, while higher percentages of semi-aquatic plant pollen imply that more moisture was available at the bog site during this period. After about 170 YBP the development of the modern piney woods vegetation is indicated by increases in pine, sweetgum, elm and yaupon pollen while herb and grass pollen declines.
