Motivated by recent findings of enhanced species survival when fragmented habitats are reconnected through narrow strips of land [S. Pimm, and C. N. Jenkins, Am. Sci. \bf 107(3), 162 (2019).], we study the effect of a corridor connecting two square regions on the survival time of three models exhibiting extinction/survival phase transitions: the basic contact process (CP), the diffusive contact process, and the two-species symbiotic contact process (2SCP). We find that connecting the regions generally increases the survival time for λ≥ λc, where λ is the reproduction rate and λc its critical value. The enhancement of the survival time increases with λ, and is largest in the 2SCP.
