This species may be found in trees, shrubs, orchards, vineyards, desert areas, and reeds generally near freshwater habitats; the species can occur at high densities within suitable vegetation. Breeding and larval development take place in ponds, irrigation ditches, temporary pools, flooded meadows, lagoons, cattle pools, wells and even swimming pools. It is sympatric in some areas of Europe with Hyla molleri (Reino et al. 2017), and seems to be displacing it.

In the European region, the Stripeless Treefrog is known from southern France, Monaco, coastal northwestern Italy (Liguria and southern Piedmont), Spain (mainland Spain, the Canary Islands, Menorca and the enclaves of Ceuta and Melilla in North Africa; Fahd et al. 2022) and Portugal (mainland and Madeira). A review of research on the origins of European subpopulations suggests that its occurrence in both mainland Europe and offshore islands represents the result of human introductions in antiquity (Dufresnes and Alard 2020). Only southern Iberian subpopulations represent potentially natural dispersal, although their haplotype patterns are best explained by human translocation (Recuero et al. 2007), however, further research is needed to clarify whether this is a result of under sampling of Moroccan subpopulations, and Dufresnes and Alard (2020) considered Iberian records to be the result of human introduction during the Bronze Age or the Phoenician era, a later but still historical introduction to the Balearic Islands, northern populations (France and Italy) to be probably founded during subsequent Roman or Arab periods, and introductions to be recent in origin in the Macaronesian islands; Canaries (late Middle Ages and Madeira (possibly resulted from naturalization efforts in the 19th century).

The species has been observed in the Alameda Gardens in Gibraltar, but no natural waterbodies exist in this territory and there are no records of a breeding subpopulation; as such these records must represent vagrants from nearby Spanish subpopulations (D. Donaire-Barroso pers. comm. 2020). In the drier parts of its range (in parts of Iberia), its distribution is fragmented due to limited available habitat, and it has a small area of occupancy (AOO) within its wider extent of occurrence (EOO). It has apparently been lost from a number of localities in southwest Spain (Paracuellos et al. 2017).

The natural distribution of this species is in the western Mediterranean, where it is native to Morocco and Algeria (Dufresnes and Alard 2020).

Conservation Actions In-Place
The species is listed on Appendix II of the Bern Convention and on Annex IV of the EU Habitats Directive. It is recorded in a number of national and sub-national Red Data Books and Lists and is protected in parts of its range by national and sub-national legislation. The species occurs in many European protected areas.

Research Needed
This species would benefit from general research into the impacts and extent of threats.
