Dendroecological techniques were applied to reconstruct stand-replacing fire history in mixed conifer and spruce-fir forests in northern New Mexico and southern Colorado. Stand-replacing fire dates with annual accuracy and precision were determined using four lines of evidence for each of twelve sites within a 75,000 square kilometer area. The four lines of evidence were: (1) aspen inner-ring dates, (2) conifer death dates, (3) tree-ring width changes, or other morphological indicators of injury, and (4) fire scars. The annual precision of dating allowed the identification of significant synchrony of stand replacing fires among the 12 sites and regional surface fire events previously reconstructed from the large network of fire scar collections in the Southwest. Nearly all of these synchronous stand-replacing and surface fire years coincided with extreme droughts. This suggests that stand-replacing fire activity occurred primarily when drought conditions allowed fires to ignite and spread within these high elevation forests and/or for the spread of surface fires between lower and upper elevations. Fifty percent of reconstructed stand-replacing fires pre-dated large-scale Euro-American settlement in this region. This may suggest that land use practices (such as logging and mining) were not as important in promoting stand-replacing fires in these study sites, as compared with other areas in Colorado.

Fire-scar analysis to identify fire events and stand age structure analysis to identify fire effects on survivorship of trees were used to reconstruct surface and crown fire regimes in upper elevation forests of the Gila Wilderness, NM. Fire regimes varied across forest type, but not necessarily across elevation. Prior to the twentieth century, (from 1706 to 1904), the mean interval for large fires was 8 years. During the twentieth century, (from 1904 to 1995), the mean fire return interval for large fires was 46 years. The virtual end of historically frequent fire regimes due to livestock grazing and fire suppression since the turn of the century has affected successional pathways of forest types across elevations, favoring later successional forest species and structures.

The purpose of this research was to reconstruct and interpret the history of fire in the Organ Mountains, New Mexico. I used dendrochronological techniques to date fire scars on 90 trees comprising ten sites within the Fillmore Canyon watershed. Two fire regimes were identified during the pre-settlement period. Fire Regime I, 1650-1805, was characterized by a high fire frequency (ca. once every two years) and a predominance of patchy fires. Fire Regime II, 1805-1874, was characterized by a lower fire frequency (ca. once every 3.5 years) and a predominance of widespread fires. During the post-settlement period fire was virtually non-existent. I hypothesize that Apache use-of-fire influenced patterns during the pre-settlement period, while Euro-American land use activities influenced patterns during the post-settlement period. Fire-precipitation associations suggest that low fuel moisture levels were a pre-condition for widespread fires.

INTRODUCTION

A second collection trip was made to the Pueblo de Acoma the week of October 12, 1987. The crew consisted of the author and Jeffrey S. Dean, both from the Laboratory of Tree-Ring Research.

The purpose of the trip was to complete those units in Area H that had been bypassed in April 1987. However, since the expected HUD funding had not yet been received, the Restoration Project was not active and the Area H units were still unavailable. As a consequence, only a single unit was cored in Area H with the remainder of the work done in Area F and Area C.

In addition, we had the opportunity to survey Cebolleta Mesa and adjacent areas for living trees, particularly pinyon (Pinus edulis), that might be old enough to overlap with the beams cut in the mid 1600s. This of course would mean trees of an age class of 350 \– 400 years; not impossible for pinyon, but relatively rare. We located two sites, one near Indian Lake on Cebolleta Mesa and one at Mesa Negra Spring at the western edge of the reservation. Both sites should be tested for tree age to determine if full coring is warranted.

For both these activities, coring at Sky City and reconnaissance, we were accompanied by Marvin C. Garcia and Dwight Lucario. Our accomplishments are due in large part to their helpfulness and good humor.

INTRODUCTION

Two final collection trips were made to the Pueblo de Acoma the week of May 15, 1988 and the week of July 19, 1988. The crew again consisted of the author and Jeffrey S. Dean, both from the Laboratory of Tree-Ring Research.

Once again the purpose of the trips was to complete work in Area H that had been bypassed on previous visits. This work was in fact completed during the second trip, but the May trip was diverted to work in Area A and Area B because Area H was not yet cleared of household goods. We were fortunate during the May visit to locate a number of structures, uninvolved with the Restoration Project, whose owners gave us permission to core.

A considerable amount of time on both trips was spent comparing the plans of the Restoration Project with the plans drawn by the Historic American Buildings Survey in 1934 (Nabokov 1986; see reference in the initial report). As a result, a concordance of the numbering systems was developed (Table 2) to serve as a measure of architectural chance between 1934 and 1988. One unit could not be identified with any certainty and the units in Area F are less than certain. All others are, however, clearly cross referenced.

INTRODUCTION

In the spring of 1986, the Laboratory of Tree-Ring Research was contacted by the Laboratory of Anthropology, Museum of New Mexico regarding participation in archaeological clearance of the Pueblo de Acoma (Sky City) Rehabilitation Project. This project, funded by a Department of Housing and Urban Development (HUD) Community Development Block Grant, had been ongoing since 1982 but only recently had considered compliance with the National Historic Preservation Act of 1966 (Section 106).

A meeting and field inspection was held at Acoma in September 1987 with representatives of the Sky City Rehabilitation Project (Vallo), the Museum of New Mexico (Ware, Adams, Ladd), and the Laboratory of Tree-Ring Research (Robinson, Dean). This meeting resulted in, among other things, a commitment from the Laboratory of Tree-Ring Research to participate in the archaeological clearance and to seek its own funds to do so. As a consequence, a proposal and a budget covering the field work was submitted to a local Tucson foundation and funding was obtained. In the meantime, the Museum of New Mexico continued to work with the Pueblo de Acoma and HUD in developing an application for a new Block Grant.

A second meeting was held at Acoma in January 1987 to discuss implementation of the cooperative agreement. In addition to the previous representatives, the Rehabilitation Project consulting architect (McHenry) and the Bureau of Indian Affairs archaeologist (Harrill) were present. Specific clearance of Area H was discussed and it was agreed that the Laboratory of Tree-Ring Research project should be implemented in advance of construction and that some sampling in Area C would be possible in late April 1987.

A final meeting was held in the council chambers of the Pueblo de Acoma on April 21, 1987 with homeowners in Area H whose houses were targeted for rehabilitation in 1987. In addition, the meeting was attended by First Lt. Governor Ray Histia, Mr. Greg Histia of the Acoma Development Authority, Mr. Dennis Vallo and Mr. Marvin Garcia of the Rehabilitation Project, and Dr. John Ware and Mr. Tom Livesly of the Museum of New Mexico as well as the Laboratory of Tree-Ring Research crew. Discussions were held regarding scheduling and coordination of the Laboratory\’s work and the concerns of the homeowners. Many homeowners asked questions about how vigas were sampled, how much time it would take, and whether any disturbance would occur. At the conclusion, all homeowners expressed satisfaction and real interest in the project.

A data base of fire occurrence was established for the Gila Wilderness by analyzing fire scars and compiling fire records. Cross sections of 44 fire scarred ponderosa pine trees (Pinus ponderosa Laws.) were collected from three study areas. Crossdating of more than 800 individual fire scars revealed that extensive surface fires were a common occurrence prior to 1900. Mean fire intervals for a 250-year period prior to 1900 were approximately four to eight years and fire intervals ranged from one to 26 years. Intensive grazing and fire suppression efforts after 1900 resulted in a sudden decrease in number of fires recorded by the sample trees.

A 72-year record (1909-1980) of fire occurrence in the Gila National Forest was compiled from Forest Service records. The fire records and fire scar evidence suggest a need for continued emphasis on fuels reduction and greater flexibility in the Prescribed Natural Fire program.

Wooden beams and planks from the Spanish Colonial church and other structures in Las Trampas, north-central New Mexico, have been sampled and dated by dendrochronology. Dates of AD 1735 imply Spanish occupation of the area 16 years prior to official grant. Stockpiling of timber for church construction began as early as 1758. Exterior walls were 15 feet high by 1762 and were completed to roof level by 1764. Late in 1776, wood was cut for a dust-guard over the adobe altar and mural. According to clustering of tree-ring dates, a new altar and wooden altar screen were constructed soon after 1785.

Beam re-use was prevalent. Timbers bearing early dates were incorporated into the 1785 altar screen, indicating re-use from within the church of from other pre-1760 structures. A roof viga was later used as a floor plank after reroofing. In domestic buildings, re-use of beams is repeated.

Replacement of beams supporting the balcony was made in the 1860\’s and 1870\’s. Tree-ring dates indicate repairs again in the 1930\’s and 1943.

A survey of the literature pertaining to dendrochronology of historical sites revealed that shaping of beams and lack of thorough sampling have heretofore hindered successful application. The documentary record of Las Trampas art and architectural history has been further refined by tree-ring dating, and the study reaffirms the potentials for historical sites dendrochronology.
