Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

common sea-lavender

<em>Limonium vulgare</em>, the common sea lavender, is a perennial halophytic plant in the family Plumbaginaceae, order Caryophyllales, native to saltmarshes and coastal mudflats of Europe and North America. This species is a characteristic component of mid-marsh vegetation zones, thriving in the periodically inundated, saline soils of estuaries and tidal flats. It produces dense clusters of small, lilac-purple flowers on branching stems from late summer onward, providing an important nectar source for pollinators. Critically, <em>Limonium vulgare</em> is classified as Endangered by the IUCN, reflecting severe population declines driven by saltmarsh loss, coastal development, sea-level rise, and agricultural conversion of intertidal habitats. Its restricted habitat specificity makes it particularly vulnerable to coastal modification. Conservation efforts for this species focus on protecting and restoring saltmarsh ecosystems across its declining range. Biological traits for this species remain poorly documented in the scientific literature, including comprehensive quantitative data on individual lifespan, precise plant dimensions, and dietary ecology, though its photosynthetic, halophytic strategy and pollinator relationships are recognized aspects of its biology.
