Method synopsis

Shade cloths suspended 3m above treatment plots accelerate snowmelt by 5-7 days when snowpack reaches ~1m depth, simulating earlier spring snowmelt conditions. Cloths removed after complete treatment plot snowmelt.

Synthesized from method descriptions across 22 papers 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 — Differences in individual flowering time change pollen limitation and seed set in three montane wildflowers (2023), American Journal of Botany. The protocol was originally introduced by How does altered phenology affect pollination and reproduction of <i>Delphinium nuttallianum</i>? (2013). Implementations in other papers (listed below) may differ.

1. Apply snowmelt acceleration treatment
   Accelerated snowmelt treatment plots received black 50% woven plastic shade cloth placed over snowmelt areas five to six weeks before anticipated natural snowmelt date. Shade cloths were removed when 80% of snow in plots was completely melted to the ground.
   Quantities: 50% shade cloth coverage, applied 5-6 weeks before natural snowmeltDuration: 5-6 weeks until 80% snow melt achievedConditions: Applied during late winter/early spring snowpack period
   Equipment: black 50% woven plastic shade cloth

Typical Equipment

• shade cloths
• 3m rebar stakes
• PVC poles

Output Measurements
