Biodiversity perception plays a significant role in shaping ecological restoration and conservation efforts together with landscape design strategies. This study examines the relationship between measured and perceived biodiversity by comparing conventional and experimental afforestation approaches consisting of five planting typologies in total. Using 20x20 m plots with varying tree-to-bush ratios and a control plot with natural vegetation succession, biodiversity was measured mathematically by using the Shannon-Wiener Index while the perception of biodiversity was assessed through a survey featuring visual stimuli with the participation of 163 individuals with varying educational backgrounds of landscape architecture, architecture, and environmental sciences. The findings indicate that, overall, measured and perceived biodiversity rankings were mostly aligned; however, slight differences surfaced in specific typologies. Participants tended to associate biodiversity with visual characteristics such as plant density, structure, and color as well as species richness. The outcomes highlight the importance of designing afforestation projects that enhance ecological value together with public perception of biodiversity. This research was developed with the kind collaboration of the National Biodiversity Future Center (NBFC) Project, specifically under Spoke 5, Task 6.3 – Restoration Ecology, which provided the scientific and structural foundation for assessing biodiversity restoration strategies through afforestation typologies.
La percezione della biodiversità gioca un ruolo significativo nella definizione delle strategie di ripristino ecologico, conservazione e progettazione del paesaggio. Questo studio esamina la relazione tra biodiversità misurata e percepita, confrontando approcci di riforestazione convenzionali e sperimentali costituiti complessivamente da cinque tipologie di impianto. Utilizzando parcelle di 20x20 m con differenti rapporti tra alberi e arbusti, oltre a una parcella di controllo con successione naturale della vegetazione, la biodiversità è stata quantificata matematicamente attraverso l'Indice di Shannon-Wiener, mentre la percezione della biodiversità è stata valutata tramite un questionario basato su stimoli visivi con la partecipazione di 163 persone con diversi background formativi (architettura del paesaggio, architettura e scienze ambientali). I risultati indicano che, complessivamente, le classificazioni della biodiversità misurata e percepita sono in gran parte allineate; tuttavia, sono emerse lievi differenze in alcune tipologie. I partecipanti tendevano ad associare la biodiversità non solo alla ricchezza specifica, ma anche a caratteristiche visive come densità, struttura e colore della vegetazione. Questi risultati evidenziano l'importanza di progettare interventi di riforestazione che migliorino sia il valore ecologico che la percezione pubblica della biodiversità. Questa ricerca è stata sviluppata grazie alla gentile disponibilità e collaborazione del National Biodiversity Future Center (NBFC), in particolare nell’ambito dello Spoke 5, Task 6.3 – Restoration Ecology, che ha fornito la base scientifica e strutturale per la valutazione delle strategie di ripristino della biodiversità attraverso diverse tipologie di riforestazione.

Abstract
Biodiversity perception plays a significant role in shaping ecological restoration and conservation efforts together with landscape design strategies. This study examines the relationship between measured and perceived biodiversity by comparing conventional and experimental afforestation approaches consisting of five planting typologies in total. Using 20x20 m plots with varying tree-to-bush ratios and a control plot with natural vegetation succession, biodiversity was measured mathematically by using the Shannon-Wiener Index while the perception of biodiversity was assessed through a survey featuring visual stimuli with the participation of 163 individuals with varying educational backgrounds of landscape architecture, architecture, and environmental sciences. The findings indicate that, overall, measured and perceived biodiversity rankings were mostly aligned; however, slight differences surfaced in specific typologies. Participants tended to associate biodiversity with visual characteristics such as plant density, structure, and color as well as species richness. The outcomes highlight the importance of designing afforestation projects that enhance ecological value together with public perception of biodiversity. This research was developed with the kind collaboration of the National Biodiversity Future Center (NBFC) Project, specifically under Spoke 5, Task 6.3 – Restoration Ecology, which provided the scientific and structural foundation for assessing biodiversity restoration strategies through afforestation typologies.| File | Dimensione | Formato | |
