Abstract
We planted 40 saplings of 11 old-growth forest tree species in 57 sites: 14 pasture lands, 10 shaded-coffee plantations, and 36 young secondary forests in Tropical Montane Cloud Forest landscapes in Mexico. We recorded sapling survival and relative growth rate in height (RGRh) over two years. We tested the survival and growth response for all species together to the effects of elevation, Climate Moisture Deficit, landuse (pastures, coffee, secondary forests), and level of care provided after planting (no-care, limited-care and full-care) during the first and second years.

Description of the data and file structure
The data set includes the survival and growth rates of 11 old-growth forest tree species after two years of planting across 57 sites in Mexico.
site_id = number of site in the restoration project
latitude = Latitude (decimal degrees, WGS84) of the restoration site where tree saplings were planted. To protect the privacy of participating landowners, the geographic coordinates of restoration sites have been spatially generalized.
longitude = Longitude (decimal degrees, WGS84) of the restoration site where tree saplings were planted. To protect the privacy of participating landowners, the geographic coordinates of restoration sites have been spatially generalized.
Latitude and longitude values correspond to the centroid of each restoration site.Identical coordinates occur because multiple trees or observations were recorded within the same site.
species codes
JP = Juglans pyriformis
PL = Persea longipes
PS = Persea schiedeana
QD = Quercus delgadoana
QM = Quercus meavei
QCa = Quercus calophylla
QCo = Quercus cortesii
QG = Quercus germana
QP = Quercus pinnativenulosa
QS = Quercus sartorii
QX = Quercus xalapensis
elevation = elevation at planting site (m a.s.l.)
CMD = Hargreave’s Climate Moisture Deficit
landuse = pastures, coffee (shaded coffee plantation), secondary forest
care_1 = care provided to the planting during the first year, coded in three categries: (1) no-care, which included planting sites that showed no evidence of active management since establishment. These sites were characterized by dense herbaceous or climber cover surrounding seedlings (often overtopping them), absence of recent weeding, and/or evidence of damage by livestock (e.g. browsing, trampling, or broken stems). No physical barriers (e.g., fencing) or maintenance interventions were observed, (2) limited-care, which corresponded to planting sites that received occasional or irregular management. These sites were free of herbaceous cover at the time of assessment but exhibited signs of previous prolonged vegetation cover (e.g., residual dry biomass, partially suppressed seedlings), or intermittent livestock disturbance. Management actions likely included one weeding event after planting, and/or incomplete livestock exclusion (e.g., damaged or partial fencing), and (3) full-care, which included plantings that received consistent and sustained maintenance throughout the monitoring period. These sites were characterized by repeated vegetation control (typically ≥2 weeding events per year), producing seedlings free from herbaceous competition. In addition, effective livestock exclusion was evident (e.g. intact fencing) and no signs of browsing or trampling were observed..
care_2 = care provided to the planting during the second year, coded in three categries: (1) no-care, which included planting sites that showed no evidence of active management since establishment.

height_0 = tree sapling initial height at planting time (cm)
surv_0 = survival of tree saplings one month after planting (1 = alive, 0 = dead)
surv_1 = survival of tree saplings after one year (1 = alive, 0 = dead)
surv_2 = survival of tree saplings after two years (1 = alive, 0 = dead)
RGR_2 = Relative Growth Rate in height (cm / cm y)
NA = Not available data

A total of 57 forest sites were selected to establish the plantings in field common gardens spanning an elevational range from 1,051 to 2,519 m a.s.l in Veracruz, Mexico. In each site, 40 seedlings of 11 old-growth forest tree species were transplanted in 2023. Survival, height, and category of care observed were recorded after one and two years. The relative growth rates in height (RGR) were calculated following Hunt (1982).
We tested the climate sensitivity of the young tree stages using the Hargreave’s Climate Moisture Deficit (CMD). The climate data for each site (average 2022-2024) were downloaded from the ClimateNA data portal (https://climatena.ca/), based on Wang et al. (2016).
