This species is a large tree which is native, and possibly endemic, to Java. However, there is considerable uncertainty as to the true distribution of this species, with several sources stating that it is much more widespread, occurring elsewhere throughout Indonesia, on peninsular Malaysia and also in the Philippines. The most recent taxonomic sources, however, suggest that it is only found in Java, though no explanation for the exclusion of non-Javan specimens from this species concept could be found. The single known specimen from peninsular Malaysia has been reviewed and re-determined as Ficus deltoidea var. deltoidea and it is therefore possible that the other non-Javan specimens have also been re-determined as different species, though this information does not appear to be available. Additionally, many Ficus species, including Ficus sundaica, which has been described as possibly conspecific, occur throughout Java, meaning the true identification of the known Javan specimens is also unclear. Consequently, it is not possible to accurately estimate the extent of occurrence (EOO) or area of occupancy (AOO) of this species. Based on the Javan specimens alone, the EOO could be up to 20,950 km², which only just exceeds thresholds for a threatened category under criterion B1. However, if the species is shown to be far more widespread, the EOO could be up to 3 million km². The revision of all known specimens is needed in order to determine the true distribution of this species. Additionally, the majority of Javan specimens were recorded over 100 years ago and aside from reports in the literature of this species' continued presence on Java, no recent specimens have been collected. This makes it very difficult to determine the current state of the population. Habitat loss and degradation has been severe and widespread across Java, with very little natural habitat remaining except in montane areas. This species tends to grow at the bottom of montane slopes and therefore often just outside of protected areas, leaving it vulnerable to logging. The majority of localities from which this species has been recorded from Java appear from satellite imagery to have experienced partial or complete habitat loss, which leaves the current status of these subpopulations highly unclear. If taxonomic work reveals this species to be endemic to Java, it is likely to fall into a threatened category under criterion B. Further research into the population of this species as well as its generation length is needed in order to assess it under criterion A, C or D. Due to the uncertainty in this species' distribution, it is assessed here as Data Deficient until it can be confirmed which specimens actually represent the species.

The distribution of this species is currently unclear. It is certainly native to Indonesia where it is potentially endemic to Java. However, it is also possibly present on Sumatra, Bali, and Kalimantan on Borneo. It is also apparently present in Sabah province on Borneo as well as on the Malay peninsula (Soepadmo and Saw 2000). Additionally, there are records from the Philippines (Corner 1965, Pelser 2022). However, the most recent taxonomic sources consider this species to be endemic to Java (Berg and Corner 2005, POWO 2023). In spite of this, it is unclear as to why specimens from outside Java have not been accepted by these authors as part of the species distribution and non-Javan specimens examined through online herbaria have shown no new determinations. However, a review of the only known specimen from the Malay peninsula (Nur #32551) which was determined as Ficus involucrata by Corner, has recently been re-determined as F. deltoidea var. deltoidea (H. Beentje, pers. comm. 2023). This suggests that other specimens may also have been incorrectly identified and Flora Malesiana (Berg and Corner 2005) notes that the species may even be conspecific with the widespread Malesian species F. sundaica. Review of the known material of this species is needed in order to confirm what its true distribution is. This includes the Javan specimens, as many other Ficus species, including F. deltoidea and F. sundaica are also present on Java. Due to the difficulty in assessing the distribution of this species, its elevational range is also uncertain. However, it is thought to grow at elevations from 500 up to 1,700 m asl (Berg and Corner 2005), though becoming rare beyond 1,500 m asl (Meijer 1959).

There is no information on the population size or current trend of this species. However, it has been reported as a dominant species at multiple sites on Java including Mount Ciremai (Hayati et al. 2021), Gentong Hill Munt Ungaran (Kurniawan et al. 2022) and between 700–800 m asl on the slopes of Mount Gede-Pangrango (Zuhri and Mutaqien 2013). This indicates that it is at least locally common where it occurs.

This species is a large, hemi-epiphytic or, rarely, terrestrial tree (Berg and Corner 2005). It grows mostly at the bottom of montane slopes where water is readily available and though it does occur in pre-montane forests up to 1,700 m asl, it becomes rare beyond 1,500 m asl (Meijer 1959, Hayati et al. 2021).

Due to the uncertainty in the distribution of this species, it is difficult to assess the scope of current threats likely to be affecting it. However, regardless of whether it is a Javan endemic, or more widespread throughout southeast Asia, habitat loss and degradation is very likely to have already affected, or to be currently impacting either its habitat or its population directly. Southeast Asia is a global deforestation hotspot, with rates of habitat and biodiversity loss being amongst the highest in the world. Between 1990–2010, the region was experiencing an average loss in forest cover of 1.6 million hectares per year (Stibig et al. 2014). 

When considering just this species' range in Java, where it is definitely considered to occur, the majority of records are from areas that satellite imagery shows to have been either partly or entirely deforested, generally for agricultural use or human settlements. Remaining intact forest on Java is now almost exclusively restricted to montane areas, the majority of which are also protected (Nijman 2013). Lowland areas have been largely deforested, with this deforestation mainly taking place between the late 1800's and early 1900's, and again during the 1940's and 1960's (Whitten et al. 1997). Current rates of deforestation are slow, though this is primarily because most remaining forest occurs only at high elevations within protected areas. Almost all of the Javan specimens were collected over 100 years ago and therefore there is considerable uncertainty as to whether the species is even still present at any of these localities. However, recent surveys have shown that the species is still present in several areas (Zuhri and Mutaqien 2013, Hayati et al. 2021, Kurniawan et al. 2022). Additionally, it generally grows at the bottom of montane slopes and therefore it is usually found just outside, or on the borders of protected areas and this is confirmed by mapping its distribution against protected area maps (UNEP-WCMC and IUCN 2023). It seems highly probable that this species will have experienced high levels of habitat loss and potentially subsequent population declines. Remnant individuals may still occur in small forest patches, though as these are unprotected, they would also remain at high risk of disturbance or deforestation.

There are no recorded uses for this species.

This species is not found in any ex situ collections held by botanic gardens (BGCI 2023). On Java, it is potentially found on the borders of Gunung Gede-Pangrango National Park and Gunug Tilu Nature Reserve (UNEP-WCMC and IUCN 2023). It is also apparently present in Gunung Ciremai National Park (Hayati et al. 2021).
