Historical Accounts of Vegetation Communities ~1700-1900

Project History

  • Work in progress

  • Started in early 1990s

  • Questioning popular assumptions, such as…

    • The Hill Country was originally dominated by grasslands that have been invaded by woodlands due to overgrazing/over-browsing and fire suppression

    • Native Americans burned on a regular basis

    • Ashe juniper is not native, invasive, etc.

  • “…present-day patterns of vegetation in the Texas Hill Country have shifted from rolling hills clothed with tall grasses. One of the most striking differences in the landscape is the large area that now is covered with dense cedar brakes—extensive stands of tall shrubs and trees dominated by Ashe juniper, commonly known as cedar.”

  • Claims based on historic accounts, cite Frederick Law Olmstead (1857).

Project Outline

  • Primary eye-witness accounts (>20)
    • Missionaries, prospectors, settlers, scientists, reporters

    • Frame of reference/context for accounts:
      • Major ecological regions

      • Major historic events
        • 1700-1800
        • 1800-1850
        • 1850-1900

  • Other sources (e.g., historic maps, photos, original land grants/field survey notes)

Spatial Context for Historic Accounts: �Major Ecological Regions

Need to determine where each observer was with respect to the Balcones Escarpment – i.e., was the observer on the Blackland Prairie or in the Hill Country (hilly portions of the Edwards Plateau, Llano Uplift, and Cross Timbers)

Major Historic Events: 1700-1800

1716-1789 Spain establishes networks of missions and presidios, including the Alamo in 1718. Expeditions include daily records of observations.

“…we…travelled upstream with a desire to ford [the Guadalupe River] or reach its source. We travelled about three leagues of very rugged land owing to the heavy woods and many rocks; and at the end of the three leagues two soldiers left for upstream to reconnoiter the land. They said that it could not be traveled because it is more wooded and contains more rocks….The woods consist of oaks and junipers….” --Fray Francisco Céliz, 1719

“…going past the Balcones [Escarpment], we arrived at the river they call Alarcón [Guadalupe River]. This [travel] was an effort because of the many hills and rocks, the many arroyos formed by the hills, and some thickets that contain valuable cedar and oak timbers.”

-- Bernardo de Miranda, 1756

“Immediately before us appeared as an extensive lawn with a beautiful green sward, slightly tinged with the various flowers which decked its surface. Not a shrub or bush obstructed the monotony except the towering Live Oak…. Further to the west appeared the skirting timber thickening the further it receded and rising gradually so that mile after mile of the dark boding forest rose to our view … -- J.W. Benedict, 1839

The cedars here are not the stunted shrub-like plants found in the Northern States of the Union, but are stately trees with straight trunks, seldom more than twenty to twenty-five feet in height and one and one-half feet thick. They have a uniformly spreading crown….”

– F. Roemer, 1849

This cedar forest is a treasure to the colonists of New Braunfels, since the wood was preferred above all others on account of its durability when used in building houses and fences.”

Ashe juniper tree in New Braunfels listed as a “champion” tree in the National Register of Big Trees.

44 ft tall, 3.7 ft diameter.

“We rode [from Austin] to the Brushy Creek, 20 miles [near Cedar Park], and encamped for the night. Our road was for about 14 miles of the way over a rich rolling prairie and for about six miles through a heavy cedar brake. Cedar is the main reliance for rail timber in this section, the live oak being too gnarled for such purposes.” -- A. S. Johnston, 1855

“I have visited Austin for the first time…The surrounding country is quite beautiful…dark, steep, cedar-covered mountains rise about five miles north of the city.” -- V. Bracht, 1849

“The country on [Barton] creek presents an extensive range of cedar hills and is much broken.”

– J. De Cordova, 1858

“Beyond [San Marcos] our road approached closely the hill-range, which is made up of spurs coming down from mountains North. They are well wooded with cedar and live-oak.”

 

Behind us were the continuous wooded heights, with a thick screen of cedars; before us, very beautiful prairies….” – F.L. Olmstead, 1857

“…the mountains…are covered with cedar, and send clear crystal waters gushing from them….” – J. de Cordova, 1858

“I am getting a little afraid the sheep will take the mountains in four or five years more…. Sheep is mighty hard on the range. You can tell a sheep range before you get in two or three miles of the house, for they keep the grass eaten off plum in the ground….” – E. Burrowes, 1860

“The cedar tie business has contributed largely to the growth and prosperity of the ‘Hill City’ in the last two years, more especially the last twelve months. A gentleman connected with the Central Railroad says that two hundred thousand cedar ties have been shipped from this city during the last two years, and when it is remembered that these ties bring from sixty to ninety cents each, the reader will readily comprehend the vastness of the revenue from this source….”

–Austin Daily Democratic Statesman, September 10, 1874

“The writer knows of no region in which any species of cedar is so uniformly abundant and dominant as is the mountain cedar in the limestone country of Texas… [Mountain cedar] is the most valuable tree of the semiarid hill country of Texas.” –W. Bray, 1904

“Cedar Chopper” Culture

“With the exception of cedar, the hill timber finds a market chiefly as fuel, of which enormous quantities are consumed….Cedar likewise is extensively consumed as fuel and in charcoal burning; but its great value lies in its yield of railway ties, poles, posts, sills, and innumerable other articles which utilize its great durability.” –W. Bray, 1904

“The cedar eradication program was greatly accelerated as a result of the invention of a new type of axe [‘Kerrville Cedar Axe’] especially suited for cutting cedar trees and cedar brush. The cedar axe is a product of the Hill Country in Texas, where armies of cedar choppers have been swinging away for over thirty years. It was invented partly by accident and partly because of a real need for a better tool to do the job.” –G. Hollon, 1946

From Hollon (1946) with permission from Texas State Historical Association

“A deplorable loss of cedar has taken place from brake fires. For half a century these have periodically occurred; areas which have not been burned over are the exception. Every old settler can tell of big fires which burned for days. In July, 1901, a very disastrous fire occurred near Marble Falls, in which about 600 acres of valuable cedar were destroyed”

-- W. Bray, 1904

[Golden-cheeked Warblers] are nowhere abundant, and only to be met with in the thickest cedar brakes, and as these are fast being cut and burnt out, the bird will no doubt become still more rare.” – H.P. Attwater, 1892

“In addition to the cedar, other species of the hill timber are constantly being drawn upon for fuel and the rough construction material in demand on ranches and farms….[Mountain Spanish oak] is the most common oak in the Edwards Plateau region of Texas…The wood is good for posts and rails. It is much in demand locally for fuel, and all of the sizable trees are being cut.”

–W. Bray, 1904

“’South Gorge’ at its head under Lone Tree Hill” described as having been cleared of most of the woody vegetation and “denuded of soil down to the rock and adobe.” -- William Bray 1904
