Isotopic Eviction (Cerro Pelón)

The thermal microclimate of the monarch overwintering site is fungible, being thermodynamically and chemically converted into the global export volume of Hass avocados.

wall text

In the Monarch Butterfly Biosphere Reserve, illegal logging clears high-altitude Oyamel fir canopies to establish Hass avocado monocultures. This installation translates forensic Stable Isotope Ratio Mass Spectrometry into a literal transfer apparatus. By matching Strontium-87 signatures from Cerro Pelón volcanic soil to commercial fruit tissue, the piece visualizes supply-chain traceability. A field-grade metering unit pumps resinous fluid from a felled stump into an immature, caged avocado tree, rendering the destruction of a delicate thermal microclimate into a measurable, fungible agricultural commodity.

anchor facts used

The Monarch Butterfly Biosphere Reserve covers 56,259 hectares, but core zones like Cerro Pelón are experiencing accelerated illegal logging.
Oyamel fir trees (Abies religiosa) provide the exact thermal microclimate required for monarch winter survival.
Cleared Oyamel forests are illegally replaced by lucrative Hass avocado plantations, often controlled by local cartels to supply the US export market.

mechanism

Forensic Stable Isotope Ratio Mass Spectrometry (IRMS) — Mapping the specific Strontium-87/86 ratio of the volcanic soil in the Cerro Pelón core zone to create a unique chemical fingerprint of the protected reserve.
1. Strontium baselining
Inductively Coupled Plasma Mass Spectrometry (ICP-MS) — Combusting commercial Hass avocados purchased in US grocery stores to extract their isotopic soil signatures.
2. Commodity vaporization
Supply Chain Traceability Verification — Matching the extracted avocado isotopes against the Cerro Pelón soil fingerprint to mathematically prove the fruit was grown on illegally cleared monarch wintering grounds.
3. Spectrometric indexing
Open-source intelligence (OSINT) reporting — Publishing an automated ledger of US supermarket chains currently retailing avocados composed of Cerro Pelón's protected biosphere soil.
4. Index publication

lineage

Forensic Architecture, 'The Environmental Destruction of the Putumayo' — Extends their spatial analysis of ecocide into the molecular signature of export commodities.
Hans Haacke, 'Shapolsky et al. Manhattan Real Estate Holdings' — Replaces real estate ledgers with isotopic mass spectrometry data to map covert territorial ownership.
Center for Wood Anatomy Research (CWAR) forensic timber tracking — Appropriates their mass spectrometry methods to track what replaced the illicit timber rather than the timber itself.

curatorial qa (machine verdict, unedited)

SCORE 4/5 after 1 attempt(s)
READS: The direct fluid extraction from the felled Oyamel stump into an avocado sapling via field instrumentation, grounded by the mass spectrometry report tracking Strontium-87 against import volumes.
FAILS: Thermodynamic microclimate conversion is depicted purely as sap fluid transfer; retail supply chain tracking is relegated entirely to the paper artifact.
