Descripción
The monitoring of lizards and geckos’ community in Doñana was initiated in 2005 as part of the Monitoring Program of Natural Resources and Processes. One of the aims of this project was to obtain a temporal and continuous series of data of the presence and abundance of these species to detect changes and trends in their wild populations within the protected area. The records have been collected during spring and autumn every year between 2005-2021 by members of the monitoring team in sampling transects in different habitats (dunes and Mediterranean vegetation) when reptile activity is higher. Dataset includes species name, number of individuals, sex, life stage, behaviour, coordinates, weather description (sky conditions, temperature, rain, or wind intensity), time of the day and other remarks.

Cobertura geográfica
The study area covers the Doñana Protected Area. This includes seven ecosystems types (coastal waters, beach, dunes, forest, shrubland, sandy lakes and marshes) and 21 habitat types, 11 of them of high conservation importance – such as the Bulrush and Glasswort marsh, floodplain lakes, sandy lakes, grassland ecotones, Cork-Oak forest, shrubland, coastal Juniper forest and dunes.

Datos del proyecto
The aim of this project is to provide information about the evolution of the conservation status of Doñana. To do that, it has been designed a monitoring program of the dynamic of natural processes and the distribution and abundance of species and communities. This monitoring is generating time series of data which is being used to analyzed long-term trends.

| Descripción del área de estudio | The study area covers the Natural and National park of Doñana, including the Doñana’s Biological Reserve (RBD). |
| Descripción del diseño | The Natural Processes Monitoring Program in Doñana belong to ICTS-RBD. It was created in the 1980s. Initially it focused on birds and endangered species such as the Iberian Lynx or the Imperial Eagle. In 2003, it was extended as part of an extensive monitoring program that included other components of biodiversity and ecological processes (marsh flooding or amphibian and reptile communities). As a summary, data analysis and evaluation are made to take management decisions in a short period of time to minimize the impact of the local and global change. The results are reported annually to the National Park Office and regional authorities through annual reports. |

Métodos de muestreo
The monitoring of the reptile community in Doñana was initiated in 2005 as part of the Monitoring Program of Natural Resources and Processes. The aim was to obtain a temporal and continuous series of data in the abundance of lizards and geckos species and analyze the trends to detect changes in their populations. The records are collected annually between 2005-2021 by members of the monitoring team which perform 7 sampling transects in different habitats (dunes and Mediterranean vegetation) three times per year in the periods when reptile activity is high (March-June and September-October), with good environmental conditions (temperature between 17 and 25 ºC and absence of rain).
| Área de Estudio | The study area is located in southwest Spain in the Guadalquivir Basin and cover the Natural Area of Doñana (Natural Park with 538,35 km2 and National Park with 542,51 km2). The climate is Mediterranean sub-humid with Atlantic coast influence: wet mild winters and dry warm summers. The rainy period occurs between October and April, with a peak in December–January (yearly average precipitation is about 550 mm). Four main ecosystems are described in the area: the marsh, mobile dunes, Mediterranean shrubland with pine forests and a long beach of 30 kms. |

| Control de Calidad | The protocol used has been supervised by herpetological researchers and the data have been validated by the members who performed the transects. |
Descripción de la metodología paso a paso:
- Lizard and gecko counts are collected annually by members of the monitoring team three times per year in the periods when reptile activity is high (two samplings in March-June and one sampling in September-October), with good environmental conditions (temperature between 17 and 25 ºC and absence of rain or strong wind conditions). The method used to record the presence and abundance of lizard and gecko species (kilometric index: number of individuals/km) are the transect censuses. Individuals are visually searched along seven transects (linear or circular) that are carried out by one trained person on foot. Each transect have an established length, but the length surveyed is different (averaged 1858 ± 51.86 meters). Each transect is located in dunes or mediterranean vegetation habitats, representative of Doñana ecosystems. Two transects runs through wooden footpaths (within the Natural Park and five transects are placed on sand-trails (4 within the National Park and one in Natural Park which contains a small part of wooden footpath). Linear transects have been surveyed in the outward track direction and after waiting 15 minutes it has been again performed on the way back. This information is valid to account for species presence in the area. However, we suggest to choose the first survey performed for statistical analyses that require independence of samples. Eight species can be potentially observed during the samplings: Mediterranean house gecko (Hemidactylus turcicus), Common Wall Gecko (Tarentola mauritanica), Fringe-fingered Lizard (Acanthodactylus erythrurus), Algerian Psammodromus (Psammodromus algirus), Western Psammodromus (Psammodromus occidentalis), Carbonell's wall lizard (Podarcis carbonelli), Andalusian wall lizard (Podarcis vaucheri), Ocellated lizard (Timon lepidus). Other reptile species present in Doñana have not been included in this study as the detection with this method is very low. For instance, to detect species with a fossorial behaviour (the Mediterranean Worm Lizard Blanus cinereus) or those cryptic as adders (Vipera latastei), it is required larger investment of survey which consist in looking under vegetation, burrows or logs (there are not stones in Doñana). Data recorded during the surveys include weather description (cloud cover, temperature, rain, or wind speed), species identification, number of individuals, sex and life stage of the reptiles when possible, as well as time and georeferenced data of the observation. Between 2005-2007 data was registered in Excel file and since 2008 data is recorded with the app CyberTracker (see protocol). The protocol used has been supervised by herpetological researchers and the data have been validated by the members who performed the transects. Díaz Paniagua, C., & Rivas Carballo, R. 1987.
