Managing pastoral landscapes: remote survey of herding infrastructure in Huancavelica, Peru

Open access
Whitlock, Bethany, Van Valkenburgh, Parker, Wernke, Steven A.·2024·Antiquity

Abstract

Recent archaeological research in the Andes suggests that Indigenous herders carefully managed their environments through the modification of local hydrology and vegetation. However, the limited geographical scale of previous research makes it challenging to assess the range and prevalence of pastoralist land management in the Andes. In this article, the authors utilise large-scale, systematic imagery survey to examine the distribution and environmental contexts of corrals and pastoralist settlements in Huancavelica, Peru. Results indicate that corrals and pastoralist settlements cluster around colonial and present-day settlements and that a statistically significant relationship exists between pastoral infrastructure and perennial vegetation. This highlights the utility of remote survey for the identification of trans-regional patterns in herder-environment relationships that are otherwise difficult to detect.

TL;DR

Large-scale satellite imagery survey in Huancavelica, Peru, finds pastoral infrastructure clusters around colonial and present-day settlements and that estancias are preferentially located near productive, perennial vegetation. The study demonstrates remote survey can reveal trans-regional herder–environment patterns.

Key findings

  • Surveyed 12,199 km²—about 49% of the Department of Huancavelica—and identified 6,580 corral loci and 686 estancia loci; the contiguous survey zone contained 1,735 corrals and 283 estancias.
  • Optimised hot-spot analysis in the contiguous zone shows corrals and estancias cluster around Huancavelica city and adjacent mercury mines; estancia hot spots concentrate along the upper “Mercury Road,” while corral hot spots are broader and align with the corridor connecting Villa de Arma and Castrovirreyna.
  • Estancias have significantly higher mean NDVI than corrals (p < 0.0001) and random points (p = 0.0483), and significantly lower mean NDVSI than corrals (p = 0.00444), though not significantly different from random points (p = 0.4320). Corrals have the highest mean NDVSI of all datasets, suggesting their use was not dependent on year-round pasture access.
  • Table 2 reports mean elevations of 4182 m for corrals (n = 6580), 4357 m for estancias (n = 686), and 3871/3886 m for matched random points.

Methods

  • Used GeoPACHA systematic imagery survey with 2 × 2 km grid cells, combining north–south and east–west transects with a contiguous survey zone; loci were assigned type, subtype and confidence probability, then verified by regional and general editors. Corral loci ranged from single corrals to complexes with upwards of 20 individual corrals; an estancia was defined as a locus containing corrals and domestic structures.
  • Environmental analysis used NDVI and NDVSI satellite indices, with zonal statistics calculated over a 1 km polygon around each feature to represent accessible pasture; observed distributions were compared against random points using unpaired t-tests.
  • Spatial clustering used optimised hot-spot analysis (Getis-Ord Gi*) with distance bands of 3 km for corrals and 6 km for estancias and a 500 m cell size; colonial-period notarial records from Huancavelica were used to interpret settlement patterns.

Limitations

  • The paper states that remote survey lacks chronological specificity, that stone corrals are difficult to date, and that the analysis assumes broad equivalence between past and present Andean environments and inter-annually stable bofedales; it also notes that past environmental fluctuations may have altered bofedal prevalence and herder reliance on them.
  • The paper states that NDVI can be misleading in high-elevation settings because productivity tends to decline with altitude, potentially skewing comparisons; it also notes that corral NDVSI results contradicted the earlier hot-spot finding when analysis broadened beyond the contiguous survey zone.
  • Evident in the text: hot-spot analysis is limited to the contiguous survey zone, and transect-based survey carries a potential for over-sampling certain elevations, though the authors report their survey area was largely comparable to the broader region in average elevation.

    Pastoral landscapes are well-suited to imagery survey, as corrals and estancias are visually distinctive and often situated in areas of sparse land cover.

    Evaluating the chronology of corrals and estancias using satellite data is difficult, just as it is in field-based research: stone corrals are challenging to date and efforts to date them via excavation and surface collection are rarely scalable.

    Vining and Williams (2020) found that route corridors between Tiwanaku and its colonies are associated with higher biotic productivity, indicating that the need for pasture along the route led communities to foster the development of high-value pasture.

    How intensification transformed long-held relationships between herders, animals and their environments remains unclear.

    “The need to intensify herding activity to sustain greater numbers of caravans likely impacted pastoral ecologies, but how this intensification transformed long-held relationships between herders, animals and their environments remains unclear.”

    Pre-Hispanic Andean pastoralism includes two parallel orientations: caravanning and fibre production.

    “While pre-Hispanic Andean pastoralism is often glossed as a single strategy, it really includes two parallel orientations: caravanning and fibre production.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
