Fire frequency for the desert grasslands was inferred from synchronous intercanyon fire events. Mean fire intervals range between 4-8 years in canyon pine-oak forests, 4-9 years in the intervening desert grasslands, and 5-9 years in the mixed-conifer forests. Riparian canyon pine-oak forests were important corridors for fire spread between the desert grasslands and higher-elevation forests. The decline of post-settlement (&amp;gt;1870s) fires typical of most forests in U.S., is not evident south of the border in Mexico.&lt;/p&gt;&lt;p&gt;Documentary evidence reveals the Apache had detailed knowledge of fire, that burning practices were controlled and limited, and ecosystem enhancement through intentional burning was not suggested. However, the common exception was burning practiced during wartime periods, principally by the Apache but also by the Spanish, Mexicans, and later Americans. Fire reconstructions indicate that wartime-period fires were significantly more frequent than peacetime periods at several canyon-rancherÍa sites.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>23</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Douglass, A.E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">El Cometa de Halley</style></title><secondary-title><style face="normal" font="default" size="100%">Tucson Citizen</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">astronomy</style></keyword><keyword><style  face="normal" font="default" size="100%">comet</style></keyword><keyword><style  face="normal" font="default" size="100%">Douglass</style></keyword><keyword><style  face="normal" font="default" size="100%">espanol</style></keyword><keyword><style  face="normal" font="default" size="100%">halley</style></keyword><keyword><style  face="normal" font="default" size="100%">historic</style></keyword><keyword><style  face="normal" font="default" size="100%">newspaper</style></keyword><keyword><style  face="normal" font="default" size="100%">spanish</style></keyword><keyword><style  face="normal" font="default" size="100%">tucson</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1910</style></year></dates><pub-location><style face="normal" font="default" size="100%">Tucson</style></pub-location><notes><style face="normal" font="default" size="100%">This title is available through the Tree Ring Laboratory; please contact the lab for more information. </style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Douglass, A.E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Indicacinoes sobre un period lluvioso en el Sur del Peru</style></title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Douglass</style></keyword><keyword><style  face="normal" font="default" size="100%">historic</style></keyword><keyword><style  face="normal" font="default" size="100%">peru</style></keyword><keyword><style  face="normal" font="default" size="100%">rainy period</style></keyword><keyword><style  face="normal" font="default" size="100%">spanish</style></keyword><keyword><style  face="normal" font="default" size="100%">sur</style></keyword><keyword><style  face="normal" font="default" size="100%">wet period</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1892</style></year></dates></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>13</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Douglass, A.E.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">La Inundacion de 1868</style></title><secondary-title><style face="normal" font="default" size="100%">El Cosmos</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">astronomy</style></keyword><keyword><style  face="normal" font="default" size="100%">climate</style></keyword><keyword><style  face="normal" font="default" size="100%">Douglass</style></keyword><keyword><style  face="normal" font="default" size="100%">environment</style></keyword><keyword><style  face="normal" font="default" size="100%">inundacion</style></keyword><keyword><style  face="normal" font="default" size="100%">spanish</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1892</style></year></dates></record></records></xml>
