Getting to know the species
Hermann’s tortoise
Testudo hermanni
Testudo hermanni: identity, origin and responsibility. An introductory profile for understanding the species without oversimplifying its needs.
An authentic photograph from the Guardians’ archive.
Testudo hermanni is a land tortoise associated with European Mediterranean habitats. Wild populations occur in Italy: encountering one does not mean you have found an animal to take home.
One animal, many settings
Scrub, vegetation and habitat mosaics provide shelter and different areas to use. When considering care, recreating a decorative ‘Mediterranean landscape’ is not enough: what matters is the animal’s real ability to choose, alongside safety.
Conservation: specify scale and date
The Italian Red List profile published in 2013 gives the category Endangered. This is a national assessment from that work, not a new count or the current global category. Habitat alteration, fires and collection are among the documented problems.
The species at the heart of the project
Photographs from our archive help tell the species’ story without revealing the animals’ locations. For identification, health and documentation, we do not treat a single image as conclusive evidence.

A closer look at Testudo hermanni
Understanding a Hermann’s tortoise means reading a mosaic of habitats, not simply recognising a shell. Western and eastern populations differ: origin and individual history matter when interpreting size, growth and seasons.
Adult carapace
13–18 cm
Range of mean lengths reported in the monograph, not absolute limits for the species. [1]
Body mass
Approximately 1.25 kg
Adult value from the AnAge compendium, not an ideal weight: sex and population affect the comparison. [2]
Longevity
Several decades
The biological maximum has not been established. AnAge flags the old record of 31.7 years as an underestimate and treats anecdotal ages cautiously. [2]
Length refers to the carapace, excluding head and tail. Averages, maxima and records are distinguished: they are not growth targets or diagnoses for an individual animal.

- Indicative broad native range
European Mediterranean: separate populations from eastern Spain through southern France, Italy and the Balkans to European Turkey. Islands and historical translocations require individual interpretation; green does not mean uniform presence along every coast. [1]

Hermann’s tortoise in the Sardinian landscape
Wild presence in Sardinia
From scrubland to clearings
The regional profile describes a widespread presence on the island, but this does not mean it occurs everywhere. Garrigue, Mediterranean scrub and sunny open areas offer a mosaic of food and shelter. Its Sardinian presence is traced to prehistoric and historical times: this history cannot be inferred from a photograph of an animal alone. SardegnaForeste
Clues to look for
The horny tail tip and generally divided supracaudal scute help distinguish it from the Greek tortoise. The yellow-and-black pattern varies and is not enough on its own. Observe what is visible without turning over or restraining a wild animal to complete a checklist. SardegnaForeste
Western Hermann’s does not mean a new species
Testudo hermanni hermanni is the western subspecies, also present in Sardinia; Testudo hermanni boettgeri is the eastern one. They are two subspecies of the same species. Expressions such as ‘Sardinian Hermann’s’ describe a geographical context, not an additional species to count in the atlas. The Reptile Database
If you encounter a wild tortoise, observe it without picking it up, taking it home or moving it to another habitat. If it is injured or in danger, contact the Forestry Corps. Do not publish coordinates or precise sighting locations: learning about animals must not make them more vulnerable to collection. Sardinian Forestry Corps

Compare Sardinia’s three species →Habitat and seasonal rhythms
It lives mainly in semi-open Mediterranean habitats: clearings, scrub, rocky slopes and low-growing vegetation. Sunshine and shelter lie close together, rather than being alternatives. Most populations occur below 500 metres, although some eastern populations reach much higher elevations. Activity, summer dormancy and overwintering depend on the local climate. [1]
What it eats
It is predominantly herbivorous, seeking leaves, shoots and flowers of wild plants. Availability changes through the year; observing foraging helps explain why a single food cannot describe its ecology. [1]
Eggs, hatching and growth
Eggs are laid in the ground. The monograph reports natural incubation periods of approximately 90–124 days: not a universal countdown or an incubator setting. Temperature and context affect development. [1]
Weight alone does not tell the health story
A veterinary study of Hermann’s and Greek tortoises found considerable growth variation in captive animals. The age–weight relationship alone was not suitable for assessing the effects of rapid growth; the authors suggest also considering body length. This is an important limitation of charts promising an exact weight for every age. [3]
