Method synopsis

Regular weekly surveys to document presence or absence of target species (both plants and animals) across multiple sites and years. Used for detecting broad phenological patterns with lower temporal resolution than daily monitoring.

Synthesized from method descriptions across 1 paper using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Asynchronous changes in phenology of migrating Broad-tailed Hummingbirds and their early season nectar resources (2012), Ecology. Implementations in other papers (listed below) may differ.

1. Weekly hummingbird and flower presence surveys at Arizona sites
   Recorded presence of hummingbirds and flowers approximately once per week in pine-oak woodland at Finger Rock Canyon (1984-2010) and monitored first flowering of Castilleja tenuiflora. At Tumamoc Hill, recorded first and peak flowering of Fouquieria splendens plants weekly from 1974-1977 and 2005-2011 in a population of 15 marked plants.
   Quantities: Finger Rock Canyon: weekly surveys 1984-2010 (27 years). Tumamoc Hill: 15 marked F. splendens plants, monitored 1974-1977 and 2005-2011 (25 years of data)Duration: Weekly surveys throughout flowering/arrival seasonConditions: Finger Rock Canyon: pine-oak woodland at 1940-2213 m elevation. Tumamoc Hill: 820 m elevation, just west of downtown Tucson
