En la isla de Mallorca hay miles de mapaches. No son nativos: muchas personas los tuvieron como mascotas y luego los abandonaron. Ahora viven en la Serra de Tramuntana y su número crece cada año.
El problema empezó hace años. Cuando los mapaches son pequeños, parecen adorables, pero al crecer se vuelven fuertes y pueden arañar o morder. Muchos dueños ya no los quieren y los sueltan en la naturaleza.
Los científicos dicen que es difícil erradicar esta especie. Necesitan más información para entender su impacto en el ecosistema. Mientras tanto, el mapache sigue ocupando la isla.

Watch out, English speaker
Spanish simple past (pretérito indefinido) vs. present perfect (pretérito perfecto) trips up English speakers because English often uses simple past for both. In Spanish, 'En 2025 se capturaron 767 mapaches' uses simple past because 2025 is a finished time period, while 'han capturado' (present perfect) links to the present. If you say 'En 2025 se han capturado,' it sounds wrong—like saying 'In 2025 they have captured' in English.
English speakers often default to the infinitive after 'continue' (e.g., 'continues to occupy'), but Spanish 'seguir' requires the gerund (-ando/-iendo), not the infinitive. So 'El mapache sigue ocupando la isla' means 'The raccoon continues occupying the island,' not 'sigue ocupar.' Think of it as 'keeps on doing' rather than 'continues to do.'

Grammar spotlight
Preterite vs. Present Perfect: simple past (tuvieron, abandonaron) vs. present perfect (han capturado)
A2
The preterite (e.g., tuvieron, abandonaron) describes past actions that are completed and disconnected from the present. The present perfect (e.g., han capturado) describes actions connected to the present. In this lesson, 'En 2025 se capturaron' uses the preterite because 2025 is over.
“En 2025 se capturaron 767 mapaches.”— In 2025, 767 raccoons were captured.
⚠️ Don't mix them up: if you say 'hasta julio de 2026', use the present perfect (han capturado) because the time period extends to the present.
seguir + gerundio
A2
Seguir (to continue) followed by a gerund (gerundio) means 'to keep doing something,' emphasizing that the action is ongoing. For example: sigue ocupando (keeps occupying).
“El mapache sigue ocupando la isla.”— The raccoon is still occupying the island.
⚠️ Don't use seguir + infinitive; you must use the gerund (-ando/-iendo).

Mallorca and Invasive Species
Mallorca is part of Spain's Balearic Islands and has a unique Mediterranean ecosystem. Because of island isolation, native species often lack defenses against invaders, so introduced species like raccoons can have a serious ecological impact. Local authorities have taken control measures, but the challenge remains huge.
